A model for gene expression and regulation is shown here. Not all genes are expressed at all time, and a study of the proteins within
a cell indicates that not all of the gene products are present within a cell. Analyze the model and evaluate which statement(s) below
are correct based on the gene expression. Select ALL that apply.
A)
Inactive DNA prevents the gene expression at the earliest stage.
B)
Removal of the mRNA before it is translated can regulate the gene
expression
Regulation of the mRNA is the most efficient mechanism for reducing gene
expression.
D)
DNA, once transcribed, will produce multiple protein products with very
little regulation in the process.

The cell membrane
Explanation:
I'm majoring in Biology
Cell membrane plays a direct role in the release of this chemical from the cell. The correct option is 4.
What is stimulus?A stimulus is defined as anything that can cause a physical or behavioral change. Stimuli is the plural of stimulus. External or internal stimuli can be used.
Your body's response to medicine is an example of external stimuli. Internal stimuli include changes in vital signs caused by changes in the body.
A stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment in physiology.
Sensitivity refers to an organism's or organ's ability to detect external stimuli and respond appropriately.
The diagram depicts a human cell's release of chemical A in response to a specific stimulus. The cell membrane directly influences the release of this chemical from the cell.

Which of mendels generations was allowed to self pollinate

Mendel allowed the F1 generation plants to self-pollinate
Why Mendel allowed the F1 generation plants to self-pollinate?The parent plants in the tests carried by Mendel have recognized as the P (for parent) contemporaries.
The F1 stands for the first filial generation, which was taken on cross-pollinating the parent plants. The F2 holds for the second generation, which is accomplished after self-pollinating the F1 breeding plants.

A mom, heterozygous for type B blood, has a baby with type AB blood, what possible blood types could the baby's father have?
Select all that apply
O
A
AB
B
Answers
Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.

4. In some varieties of camelia, flower color is controlled by codominance. The two alleles are red (R) and white (W). The heterozygous genotype is expressed as red and white.
D. What is the phenotype of a plant with the genotype RR?
E. What is the phenotype of a plant with the genotype WW?
F. What is the phenotype of a plant with the genotype RW?
Answers
Answer:
D. Red
E. White
F. Red and white
Explanation:
Co-dominance is a type of non-mendelian inheritance in which the two alleles of a gene are both dominant. Hence, they are both simultaneously expressed in the organisms phenotype.
According to this question, the two alleles (red (R) and white (W)) of a color gene in some varieties of Camelia are codominant. This means that both alleles will be expressed simultaneously in organisms that contain them.
- phenotype of a plant with the genotype RR is RED because only "R" alleles are present.
- phenotype of a plant with the genotype WW is WHITE because only "W" alleles are present.
- phenotype of a plant with the genotype RW will be BOTH RED AND WHITE, because they both phenotypically express themselves.

You are given a constitutive mutant, but you are not told whether it is constitutive due to a repressor mutation (i-) or an operator mutation (oc). Determine what could be added to the system that would allow you to determine the difference between the two mutants. You will add the same thing to each and indicate the results of the experiment.
Answers
Answer:
Explanation:
Repressor molecules, as we recognize them to be proteins occur as transcription factors that may function on their binding sites within the same genome or even on a different genome.
As a result, repressor molecules behave in a trans-active manner. Operator, on the other hand, acts as a binding site mostly on the chromosome genome which can only trigger downstream genes. As a result, Operators are cis-acting.
In this scenario, if we give the system a Plasmid containing a wild-type repressor gene, the repressor molecules would only attach to the usual Operator sites.
In the 1st scenario:
The Operator is regular and normal, but I- is mutated. As a consequence, the additional extra plasmid's normal repressor molecules will stick to the operator site, causing suppression or repressed expression.
In the 2nd scenario: genome
The repressor is natural, but Oc is mutated. As a consequence, the additional extra plasmid's normal repressor molecules would not adhere to the operator region, resulting in the same Constitutive expression.

Explanation:
HIV replication requires conversion of the genomic RNA present in the infecting virus to a double stranded DNA that integrates into a human chromosome. Unlike DNA polymerase, HIV reverse transcriptase catalyzes DNA chain elongation from either a DNA or RNA template. Azidothymidine (AZT) was the first effective drug used to inhibit HIV reverse transcriptase and went into clinical use in 1987 to treat AIDS. What best describes how AZT inhibits reverse transcriptase
Answers
Answer:
AZT inhibits reverse transcriptase enzyme.
Explanation:
AZT inhibits reverse transcriptase enzyme that is used by the virus to make a DNA copy of its RNA. This Azidothymidine prevent reverse transcriptase enzyme from doing its function properly. Due to absence of this enzyme, the HIV virus is unable to make copies of its DNA and this Azidothymidine stops the life cycle of the virus and slows the growth of AIDS disease so that's why this drug was considered effective against HIV virus and used in the treatment of AIDS disease.

On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. 2. The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. A bacteriophage, or bacteria virus, injects its DNA into the bacteria. ... The DNA is then replicated when the bacteria undergo cell division. 3. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates. ... It then removes itself from the host cell's DNA and enters the lytic cycle. The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse). 4. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy.
