Question

In a DNA molecule if 32% of the nucleotides are thymine what percentage are guanine?

A) 32%
B) 36%
C) 18%
D) 64%
E) 68%

Answer 1

Answer: (C) 18%

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