A botanist has acquired a group of pea plants. All of the pea plants have yellow pea pods (the recessive form of this trait) except for one, which has green pea pods (the dominant form of this trait). The botanist decides to use a test cross to determine the genotype of the green pea pod plant for this trait. The botanist performed the test cross and found the following: 50% of the offspring had yellow pea pods and 50% of the offspring had green pea pods. Based on this information, what was the genotype of the initial green pea pod plant
Answer:
Hetezygous
Explanation:
The genotype of the initial green pod plant would be heterozygous.
Let pea pod color be represented by C (c) alleles.
First, let us assume that the genotype of the green pea pod plant is homozygous dominant, CC. This was crossed with homozygous recessive, cc.
CC x cc
Cc Cc Cc Cc
All the progeny will have Cc genotype with phenotypically green color. This is in contrast to the result obtained from the test cross in the illustration, hence the genotype of the initial green pea pod plant cannot be homozygous dominant.
Now, let us assume that the genotype is Heterozygous, Cc.
Cc x cc
Cc Cc cc cc
50% of the progeny has Cc genotype with phenotypically green color while the remaining 50% has cc genotype with phenotypically yellow color. This is consistent with the result from the illustration.
Hence, the genotype of the initial green pea pod plant is heterozygous.

In rabbits, brown coat (B) is dominant to white coat (b). A rabbit breeder wants to know the genotype of his best looking male brown rabbit using a test cross. He has brown females and white females available to conduct his breeding experiments.
Required:
a. What should be the coat color of the female he must use in this test cross?
b. If the test cross produces seven (7) brown rabbits and one (1) white rabbit, what is the genotype of the brown male rabbit?
Answer:
a. white
b. Bb
Explanation:
A test cross usually involve crossing an individual whose zygosity is unknown with a homozygous recessive version of individual of the same species.
Brown coat (B) is dominant over white coat (b). Hence, there is no way to physically distinguish between a BB rabbit and a Bb rabbit because both of them will be brown. A bb rabbit however will be white in appearance.
A test cross would therefore involve crossing the brown male rabbit with bb (white) rabbit.
Assuming that the genotype of the brown rabbit is BB, all the progeny will be brown as shown by the cross below.
BB x bb
Bb Bb Bb Bb
In order word, assuming the genotype is Bb, some of the offspring will appear brown while some will appear white.
Bb x bb
Bb Bb bb bb
Hence, the only way the test cross would produce white offspring is if the genotype of the brown rabbit is heterozygous, Bb.

O It is degraded.
O It is sliced into different sections.
Answer:
it binds together
Explanation:
dna is commonly present in the shape of a molecule with double strands. In a similar way, these two molecules connect to each other in a mechanism called hybridisation. DNA naturally, the new strand hybridizes to the old strand when it is replicated.
hope this helped!
During hybridization, DNA strands bind together. The correct option is A.
The process of joining two complementary strands of DNA from various sources to create a double-stranded molecule is referred to as hybridization.
The complementary DNA strands join together during this phase and create strong hydrogen bonds between their corresponding base pairs. Adenine (A) and thymine (T) and guanine (G) and cytosine (C) couple up specifically to form this interaction.
Numerous molecular biology procedures, including DNA hybridization tests, polymerase chain reaction (PCR), and DNA sequencing, frequently employ hybridization.
Hybridization enables the identification and amplification of particular DNA sequences as well as the analysis of genetic data by allowing the complimentary strands to come together.
Thus, the correct option is A.

If you have a concern about fluoride in your drinking water, how do you get more information?
Answer:
Contact the Centers for Disease Control and Prevention (CDC).
Explanation:
These five concepts provide a modem interpretation of Mendelian postulates.
- Inheritance is governed by information stored in discrete factors called genes.
- Genes are transmitted from generation to generation on vehicles called chromosomes.
- Chromosomes, which exist in pairs in diploid organisms, provide the basis of biparental inheritance.
- During gamete formation, chromosomes are distributed according to postulates first described by Gregor Mendel, based on his nineteenth-century research with the garden pea.
- Mendelian postulates prescribe that homologous chromosomes segregate from one another and assort independently with other segregating homologous during gamete formation.
Based on these concepts, choose statements that correlate Mendel's four postulates with what is now known about genes, alleles, and homologous chromosomes.
Select the five correct statements.
a. Some gene pairs on nonhomologous chromosomes can aggregate after separation and mitosis or meiosis would stop.
b. Some genes have dominant and recessive alleles.
c. Unit factors occur in pairs.
d. Some possible gametic combinations are formed with higher probability if dominant alleles take part in meiosis.
e. During mitosis and meiosis, when chromosomes are visible in their characteristic shapes. members of a homologous pair have different sizes and exhibit opposite centromere locations.
f. Different gene pairs on non-homologous chromosomes will separate independently from each other during meiosis.
g. Alleles segregate from each other during gamete formation at anaphase
h. Dominant alleles can become codominant alleles during mitosis.
e. One gene pair separates independently from other gene pairs.
Answer:
b. Some genes have dominant and recessive alleles.
C. Unit factors occur in pairs.
e. During mitosis and meiosis, when chromosomes are visible in their characteristic shapes. members of a homologous pair have different sizes and exhibit opposite centromere locations
f. Different gene pairs on non-homologous chromosomes will separate independently from each other during meiosis.
g. Alleles segregate from each other during gamete formation at anaphase
Explanation:
Mendel's postulates of inheritance are: (1) Principles of Paired Factors (2) Principle of Dominance(3) Law of Segregation or Law of Purity of Gametes (Mendel’s First Law of Inheritance) and (4) Law of Independent Assortment (Mendel’s Second Law of Inheritance).
Each of these laws provide information on how inheritance of traits by offspring from parents occur.
Principle of paired factors:
A character is represented in an organism (diploid) by at least two factors. The two factors lie on the two homologous chromosomes at the same locus or position.
Principle of Dominance:
Dominant characters are those which always appear in every generatio whereas recessive characters may not appear in some generations e.g. F1 generation.
Law of segregation:
During the formation of gametes (egg or pollen), the paired genes separate or segregate randomly so that each gamete receives one or the other with equal likelihood
Law of Independent assortment:
During gamete formation, segregating pairs of unit factors (genes) assort independently of each other.
From the above consideration,
Option A is wrong because it doesn't correlate with the law of Independent assortment
Option B is correct based on the second postulate
Option C is correct based on the first postulate
Option D is wrong based on the law of segregation which assigns equal likely to gene separation
Option E is correct based on recent studies of genes
Option F is correct based on the law of Independent assortment
Option G is correct based on recent studies on genes
Option H is wrong because dominant genes remain dominant. Co-dominance occurs when allelic pairs are neither dominant nor recessive
Option 'e' is wrong because independent assortment occurs between pairs of genes with contrasting character not a gene pair having the same character where only segregation occurs.
A study from the National Institutes of Health states that the human body contains trillions of microorganisms that make up 1% to 3% of the body's mass. Use this information to estimate the average mass of a microorganism.
Answer:
If the mass of the human body is 60 kg so the average mass of microorganism is 1.2 kg.
Explanation:
If we suppose the mass of human body is 60 kg and we know the percentage that is 1 to 3% so we will take the average microorganism mass of which is 2%. So by doing multiplication of 60 with 2 and then divided by 100, we get 1.2 kg. The reason for dividing by 100 is that the average mass present in percentage form so for converting the percentage into standard form we have to divide it by 100. So we conclude that in every human with a mass of 60 kg have 1.2 kg microbes present in their body.

Explanation:
Describe the typical principles used to identify topogenic sequences within proteins and how these principles can be used to develop computer algorithms. How does the identification of topogenic sequences lead to prediction of the membrane arrangement of a multipass protein
Answer:
Topogenic sequences share a series of structural features, and thereby computational algorithms can be used to predict these protein-membrane segments
Explanation:
Topogenic sequences are protein segments formed by alpha-helical transmembrane domains, which are required for the insertion of membrane proteins. These domains share a series of well-defined features: they are composed of segments of about 20 hydrophobic amino-acid residues. In consequence, computational algorithms can be designed to identify protein patterns that fulfill these structural requirements (i.e. segments with a length of 20 residues, hydrophobic level, etc). The models assign a similarity threshold (threshold value) that predict if the similarity level of the protein pattern is good enough to detect a topogenic segment.
What explains the presence in living humans of DNA sections which are identical to DNA
found in Neanderthals who lived 40 000 years ago?
Answer:
It can be explained by hybridization among human and neanderthal ancestral populations.
Explanation:
Next-generation sequencing (NGS) technologies coupled with bioinformatics tools have enabled to confirm admixture between Neanderthals and humans. The technique to identify admixture events consists in discovering nucleotide regions from neanderthal genomes that could be inserted in human genomes, thereby the observed sequence homology must be statistically significant (e-value). This emergent research field is known as paleogenomics.

Gonorrhea is a sexually transmitted infection (STI) caused by the diplococcus Neisseria gonorrhoeae, commonly called gonococcus (GC). This organism developed resistance to penicillin and tetracycline in the 1980s, after which fluoroquinolones were the recommended drugs for treating GC. Subsequent resistance to the fluoroquinolones has led to the current recommended treatment of injected ceftriaxone in combination with oral azithromycin. Although this approach continues to be effective, recent data from the CDC indicates that resistance to azithromycin is emerging.Fluoroquinolones act by inhibiting DNA gyrase, an enzyme involved in DNA replication. Resistance to this antibiotic is most commonly by a. due to a mutation in the gene that encodes RNA polymerase, an example of adaptive resistance. b. a change in the DNA gyrase target, an example of acquired resistance increased efflux of the drug from the target cell, an example of innate resistance. c. a change in the DNA gyrase target, an example of innate resistance. d. enzymatic modification of the ribosomal target, an example of innate resistance.
Answer:
The correct answer is option b, that is, a modification in the target of DNA gyrase, is an illustration of acquired resistance.
Explanation:
The activity of DNA gyrase gets inhibit by fluoroquinolones. The enzyme that combines with the DNA and prevents its supercoiling at the time of replication is termed as DNA gyrase. It is a heterotetramer, which is formed of two subunits of GyrA and two subunits of GyrB. Due to the mutation in gene gyrA, the development of resistance takes place in N. gonorrhea against fluoroquinolones.
Post mutation, gyrA exhibits lesser binding capacity with the fluoroquinolones, and thus, the development of resistance takes place within the bacteria against the fluoroquinolones. The phenomenon of the development of resistance taking place in any microbe against the specific antimicrobial agent for whom it was vulnerable before is termed as acquired resistance, thus, the given case is an illustration of acquired resistance.

After sharing your results with your mentor, you learn that six other true-breeding strains of Drosophila with the same mutant phenotype have been isolated independently in your lab. Your mentor asks you to determine if the mutants belong to the same complementation group. What is true about flies that belong to different complementation groups? What would be the outcome of crossing two strains of wingless flies that belong to different complementation groups?
Answer:
=> There will be mutation of gene in each strain.
=> The offsprings are wild type.
Explanation:
So, we are given the following main or Important information or data which I going to assist us in solving this particular Question or problem:
=> There is an isolated a true-breeding strain of wingless Drosophila.
=> " six other true-breeding strains of Drosophila with the same mutant phenotype have been isolated independently in the lab."
Therefore, the flies that belong to different complementation groups will cause MUTATION TO OCCUR ON THE SAME GENE.
Mutation will occur because here we have dual but different genomes and when you take a look at these genomes they both have a trait of recessiveness and this combination of the genomes will cause the mutation.
Quick note: on the strain, occurence if different mutation might or might not occur.

B
A chain of amino acids folded and twisted into a molecule
Three fatty acids attached to one glycerol molecule
D
A series of nitrogenous bases attached to a sugar-phosphate backbone
Answer:
B
Explanation:
Proteins are organic compounds containing carbon, hydrogen, oxygen, and nitrogen. Amino acids are compounds that consist of an R group, carboxylic acid end, and amino end. A chain of amino acids is referred to as a protein.
The statement 'a chain of amino acids folded and twisted into a molecule' describes the structure of albumin (Option B).
Proteins are macromolecules composed of a long sequential chain of amino acids linked together by peptide bonds.All proteins must be twisted and folded by a cellular mechanism called protein folding, which becomes an inactive polypeptide chain into a functionally active protein.Protein folding modifies the tridimensional (3D) conformation of a protein in order to become it into a biologically active molecule that performs specific functions (e.g., an enzyme with catalytic functions).In conclusion, the statement 'a chain of amino acids folded and twisted into a molecule' describes the structure of albumin (Option B).

How N-formylmethionine (fMet) is only associated with the 5' AUG initiation codon and not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA.
Answer:
Different transfer RNAs (tRNAs) selectively bind to N-terminal and internal AUG codons of bacterial polypeptides .
Explanation:
In prokaryotic organisms, N-formylmethionine (fMet) is coded by the start codon (AUG), thereby generating the most N-terminal residue of bacterial proteins. This residue (fMet) is a modified methionine amino acid that contains attached a formyl group to its amino group. Remarkably, it has been shown that formylmethionyl-tRNA only can bind to this initial AUG codon, while methionyl-tRNA binds to internal AUG codons.
