AnswerAll multi-cellular life forms have them. In some organisms the DNA that codes for the mitochondrion has been moved into the nucleus and become part of the DNA of the host cell, but in vertebrates the mitochondria keep their own DNA inside themselves.
Explanation:
Answer:
Mitochondria are found in all eukaryote organisms, unlike prokaryotes. Both nucleus and mitochondria have their own DNA. The DNA of mitochondria is called mitochondrial DNA. The mitochondrial DNA helps in the production of ATP that produces energy whereas the DNA in the nucleus is the genetic material of the cell.
Explanation:
The presence of DNA inside the mitochondria is because of the fact that mitochondria are believed to be a primitive bacterium that was consumed by a eukaryote and became an essential organelle of the eukaryotic cell. Today, mitochondria exist only inside a eukaryotic cell serving as the powerhouse of the cell and containing mitochondrial DNA containing 37 genes. Advantaged of DNA in both nucleus and mitochondria:Advantages of DNA found in mitochondria and nucleus are: 13 genes of mtDNA perform the function of oxidative phosphorylation.Other genes help in the formation of tRNA and ribosomes which helps in efficient protein synthesis and production of ATP.The presence of a high number of mtDNA in the cell helps in producing a great amount of energy for the functioning of the cell.For more information:

You are observing a population of squirrels that have red or black fur. Coat color in these squirrels is determined by one gene with two alleles, where red is dominant to black. In your population, you count 100 squirrels and find 84 red squirrels and 16 black squirrels. What is the frequency of the black fur allele
Assuming that the diallelic gene, which codes for fur color, express complete dominance, and following H-W equilibrium, the frequency of the black fur allele is f(r) = 0.4
--------------------------------
Available data:
Single, diallelic gene coding for fur colorRed is the dominant traitBlack is the recessive traitTotal number of squirrels, N = 10084 animals are red16 animals are blackWe need to calculate the frequency of the recessive allele.
We will say that,
R is the dominant allele that codes for redr is the recessive allele that codes for blackWe will assume complete dominance, where R completely masks the expression of r allele, so heter0zyg0us individuals express the dominant trait.
Following Hardy-Weinberg equilibrium, the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
p is the frequency of the dominant allele, q is the frequency of the recessive allele.The genotypic frequencies after one generation are
p² (H0m0zyg0us dominant genotypic frequency), 2pq (Heter0zyg0us genotypic frequency), q² (H0m0zyg0us recessive genotypic frequency).So, if we have the genotypic frequency of the recessive phenotype (black fur) we can get the allelic frequency.
We know that there are 16 black suirrelsAnd we know that the total number of individuals in the population is 100So the frequency of the black squirrels -F(rr)- in the population is,
F(rr) = q² = 16/100 = 0.16
Now, by taking the root square of this value, we will get the allelic frequency, f(r).
F(rr) = q² = 0.16f(r) = q = √q² = √0.16 = 0.4The frequency of the black fur allele is f(r) = 0.4.

Aardvarks and anteaters share the following levels of classification:
C. Phylum
D. Class
E. Order
F. Family
Aardvarks and anteaters share phylum, class, order, and family classifications. These taxonomy levels represent increasingly detailed categories. Aardvarks and anteaters are both Chordata, which includes creatures with notochords. Their warm-blooded temperament and mammary glands place them in the Mammalia class.
Aardvarks and anteaters are related but separate orders. Anteaters are Pilosa and aardvarks Tubulidentata. Finally, they share the Myrmecophagidae family, indicating evolutionary similarity and ecological roles as insectivorous mammals. Aardvarks and anteaters share categorization, although they diverge at higher levels like genus and species due to their distinct traits and evolutionary routes.

Write a short summary of each of the three phases of the Calvin Cycle:
a. carbon fixation
b. reduction
c. regeneration of RuBP
Answer:
Calvin cycle can be described under three stages:
Carboxylation: It is the fixation of CO_{2}CO2 into a stable organic intermediate. In this, CO_{2}CO2 is utilised for the carboxylation of RuBP. This reaction is catalysed by the enzyme RuBisCO and it results in the formation of two molecules of 3-PGA (3-Phosphoglyceric acid).
Reduction: These reactions lead to the formation of glucose. The steps involve utilisation of two molecules of ATP for phosphorylation and two of NADPH for reduction, per molecule of CO_{2}CO2 fixed. The fixation of six molecules of CO_{2}CO2 and six turns of the cycle are required for the removal of one molecule of glucose from the pathway.
Regeneration: For the cycle to continue uninterrupted, regeneration of the CO_{2}CO2acceptor molecule is crucial. This step requires one ATP for phosphorylation to form RuBP. To make one molecule of glucose, six turns of the cycle are required. 18 ATP and 12 NADPH molecules are used to make a molecule of glucose. Hence, for every CO_{2}CO2molecule entering the Calvin cycle, three molecules of ATP and two molecules of NADPH are required.

g A population of geckos is in a Hardy Weinberg equilibrium state and has 50 individuals of genotype AA, 100 of genotype Aa, and 100 of genotype aa. What are the predicted allele frequencies of A (p) and a (q)
The predicted allele frequencies of A (p) and a (q) are A= 0.4 and a = 0.6. The Hardy–Weinberg principle states that allele frequencies in a population will remain constant across generations in absence of evolutionary forces.
The Hardy–Weinberg principle is used in population genetics to estimate allele and genotype frequencies in a given population.
According to this model, allele and genotype frequencies in a population will remain constant across generations in absence of different evolutionary forces.
In this case, it is possible to easily calculate the allele frequencies from the data.
Genotypes:
AA = 50Aa = 100aa = 100Allele and genotype frequencies:
Allele frequency A (p) = [(50 x 2) + 100]/500 = 0.4 >> AA (q2) = 0.16Allele frequency a (q) = [(100 x 2) + 100]/500 = 0.6 >> aa (p2) = 0.36Frecuency heterozygotes Aa >> 2 x p x q >> 2 x 0.4 x 0.6 = 0.48Learn more in:

Answer:
you can find free-living mitochondrion today in animal cells or plant cells
Explanation:
No, it is not possible to find free mitochondria because there are structural mitochondrial components that are encoded in the cell nucleus.

What is north pole and south pole?
The north pole has been known as the northernmost point present on earth, and on the other hand south pole has been known as the southernmost part or point of the earth. The area present in between the south pole and north pole has said that is extremely cold and the area present near the equator is extremely hot.
The area of north pole is not the part of any country or north pole does not lie in any country. The main reason of coldness of north pole and south pole is that they do not receive any direct sunlight. The best time to visit north pole is the time of June and July because in this month the ice of the north pole is thinner as compared to other months.
The two circles of latitude never touch because they are meeting at the North Pole and the North Pole and South Pole are the only places where the lines of longitude meet and the distance is 0 miles.

How does a change in the DNA sequence affect the amino acid produced during translation?
Answer:
Changes at the nucleotide level go on to influence the translation from gene to protein expression. Changing even just one nitrogen base in a sequence can alter the amino acid that is expressed by that DNA codon, which can lead to a completely different protein being expressed. PLEASE CORRECT ME IF I AM WRONG
Explanation:
A change in the DNA sequence affects the amino acid produced during translation because it modifies the codons that will be used in this process.
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of a given organism.A mutation will alter the triplets of nucleotides or 'codons' in the resulting mRNA that is used to create a protein during translation.In consequence, this change (mutation) may eventually modify the amino acid that will be added during translation.In conclusion, a change in the DNA sequence affects the amino acid produced during translation because it modifies the codons that will be used in this process.
