Question

In translation, a cytosine in tRNA pairs opposite Question 1 options: A) uracil. B) guanine. C) thymine. D) adenine.

Relatively weak hydrogen bonds hold each in position as base pairs in DNA.

Answer 1

The answer is B) guanine.

In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). So, when in the process of translation, anticodons of tRNA pairs with codons of mRNA, the complementary bases will pair. So, cytosine in tRNA will pair guanine in mRNA.
