Does the distribution of bases in sea urchin DNA and salmon DNA follow Chargaff’s rules? a) Yes, because the %A approximately eq

uals the %T and the %G approximately equals the %C in both species. b) No, because %A + %T does not equal %G + %C in both species. c) No, because %A is higher than %T, and %G is higher than %C in both species. d) Yes, because the %A + %T is greater than the %G + %C in both species.

Answer:

A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.

Explanation:

According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.

Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.

An individual carries a heterozygote (two diff alleles on same gene) which will be located:
swat32

Answer:

B) On the same place on the same chromosome.

Explanation:

Both alleles are located on the same chromosome and present at the same place because genes come in pair. Each pair of gene is located at a specific place on a chromosome. If the two alleles present at a specific location are similar to each other, it is called homo-zygous while on the other hand, if both alleles are different from one another, they are considered as hetero-zygous.
