If a DNA strand has 32 % guanine, what percent thymine does it contain? A) 36%
B)18%
C)64%
D)32%

B

Explanation:

Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.
