Question

What does the term "complementary" mean in base-pairing?

Answer 1

Answer:

The term complementary means "matching" in base-pairing

Explanation:

What I mean by this is that each base has its complementary (matching) base.

For example, cytosine goes with guanine so the complementary base of cytosine would be guanine.

The complementary base of thymine would be adenine

Answer 2

Answer:

From The School of Biomedical Sciences Wiki. Complementary base pairing is the phenomenon where in DNA guanine always hydrogen bonds to cytosine and adenine always binds to thymine. The bond between guanine and cytosine shares three hydrogen bonds compared to the A-T bond which always shares two hydrogen bonds.
