Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What nucleotide base matches with adenine in DNA replication?

A	guanine
B	cytosine
C	thymine
D	uracil

Explanation:

Detailed explanation-1: -DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.

Detailed explanation-2: -Final answer: In DNA the complementary bases are adenine and thymine, guanine, and cytosine.

Detailed explanation-3: -In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C). RNA is the same, except that adenine always pairs with uracil (A-U).

Detailed explanation-4: -In DNA, adenine correctly pairs with thymine and guanine correctly pairs with cytosine.

Detailed explanation-5: -Definition. Adenine (A) is one of the four nucleotide bases in DNA, with the other three being cytosine (C), guanine (G) and thymine (T). Within a double-stranded DNA molecule, adenine bases on one strand pair with thymine bases on the opposite strand.
