In sea urchin DNA, which is double stranded, 17 % of the bases were shown to be cytosine (C). The percentages of the other three bases (G, A and T) expected to be present in this DNA are:

G - 8.5 %, A - 50 %, T - 24.5 %

Solution

The correct option is D $G - 17 %, A - 33 %, T - 33 %$
In a DNA of a particular species, the number of adenine(A) = thymine (T) and cytosine(C) = guanine(G). Percentage of C = G = 17% and the remaining 66% is shared by A and T i.e., A = T = 33%. Thus, C - 17%, G - 17%, A - 33% and T - 33%.
