A strand of DNA contains 10% Guanine, what
percent is Adeninc?

40% is Adenine.

Explanation:

In DNA, Guanine pairs with Cytosine and Adenine pairs with Thymine.

If a strand of DNA contains 10% Guanine, that means that it also contains 10% Cytosine.

10% G + 10% C = 20%

100% - 20% = 80% (Adenine and Thymine)

80% ÷ 2 = 40%

The strand of DNA contains 10% Guanine, 10% Cytosine, 40% Adenine, and 40% Thymine.

true is the answer : )
