Question

as dna is replicated, which dna base pair will bond to cytosine?

adenine
thymine
cytosine
guanine

Explanation:

Identify complementary base pairing rules

In DNA, nitrogenous bases pair specifically: adenine pairs with thymine, and cytosine pairs with guanine.

Determine the partner for cytosine

Following the complementary rules, cytosine always forms three hydrogen bonds with guanine.

Answer:

• adenine
• thymine
• cytosine
• guanine (Correct answer)
