In the synthesis of mRNA, an adenine in the DNA pairs with
A)adenine.
B)uracil.
C)cytosine.
D)guanine.
E)thymine.

Question

Quizplus · Accepted Answer

In the synthesis of mRNA, an adenine in the DNA pairs with uracil in RNA through complementary base pairing. Thymine is not present in RNA, so it cannot pair with adenine during mRNA synthesis. Guanine and cytosine are not the correct base pairs for adenine. Therefore, the correct answer is B) uracil.
