Similar to the comp. purine-pyrimidine relationship observed in DNA, which of these pair with adenine in RNA

Question

A. thymine

B. cytosine

C. guanine

D. uracil

Answer 1

You really should know this answer yourself, if you want ot study RNA and DNA in the future.

But the answer would be D Uracil.

Thymine is not used in RNA. Uracil replaces the thymine. Actually the difference is quite small, structure wise. When a methyl group on the thymine is converted to a hydrogen group, you will get uracil.

Answer 2

Hmmm.. maybe you should read the chapter or listen in class instead of having us do your homework for you.
