What does complementary base pairing mean?

Bases pair randomly

Adenine pairs with Guanine, and Cytosine pairs with Thymine

Adenine pairs with Thymine, and Guanine pairs with Cytosine

Each base pairs with itself

Why is DNA replication considered "semi-conservative"?

Half of the DNA is discarded during replication

Each new DNA molecule contains one old strand and one new strand

Only half of the DNA is copied

It conserves energy by using only half the bases

How does base pairing ensure accurate DNA replication?

Bases are chosen randomly to pair with the template strand

Each base only pairs with its specific complement

Base pairing determines which proteins are made

Base pairing stops mutations during replication

If DNA polymerase adds an incorrect base during replication, what might happen?

The DNA strand will stop replicating

A mutation may occur in the new DNA molecule

The enzyme will correct itself automatically

The old DNA strand will be replaced
