Question

Deamination of adenine gives what? What does it pair with?

(A) Guanine; Cytosine
(B) Adenine; Thymine
(C) Adenine; Uracil
(D) Cytosine; Guanine

Answer 1

Deamination of adenine forms hypoxanthine, which pairs with uracil in RNA.

Step-by-step explanation:

Deamination of adenine results in the formation of hypoxanthine, an unnatural base. When pairing with another base, adenine usually pairs with thymine in DNA. However, in RNA, adenine pairs with uracil. Therefore, the correct answer is (C) Adenine; Uracil.
