Question

in a DNA sample the proportion of A is 17% the amount of G+T and C will be respectively​

Answer 1

The correct answer is (A) 50% and 30%.

Explanation:

• Since DNA is double-stranded and has pairs of adenine (A) with thymine (T) and Guanine (G) with cytosine (C).

• We know the percentage of A is 17%. The value of both A and T is the same.

• Hence this becomes A + T = 17 + 17 =34%

• So G + C would become 100 - 34 = 66%, thus G + C = 66%.

• Individually both of them would be 33%.

• The base composition of DNA is A =T= 17% and G = C = 33%

• Therefore, G when added with T gives = 33 + 17 = 50% & C = 33%.
