Question

In a sample of yeast DNA, 31.5% of the bases are adenine (A). Predict the approximate percentages of C, G, and T.

Answer 1

Answer:

A = T and G = C.

A = 31.5% and so T =31.5%. this adds up to 63%.leaving 37%.

G = C = 18.5%.

Explanation:

Answer 2

DNA is a genetic material made up of purines, pyrimidines, sugar, and a phosphate backbone. The percentage of nucleotides in the DNA follows Chargaff's ratio.

The percentage of Guanine and Cytosine will be equal that is equal to 18.5%. The percentage of Adenine will be equal to Thymine which is equal to 31.5%.

Chargaff's rule states that in the DNA, the quantity between the A and T and between the G and C are equal or has the ratio of 1:1.

In the given genetic composition, the amount of Thymine is:

Thymine = Adenine

31.5 % = 31.5%

The total percent of the purines is 63%.

The remaining pyrimidine will have the 37%, such that:

Cytosine = 18.5%

and, Guanine = 18.5%.

Thus, the percentage of A and T is 63% and C and T are 37%.
