Question

multiple choice 20 points what role do complementary base pairs play in dna replication? they prevent mutations from occurring they ensure that each new dna molecule is an exact copy of the original. they help the dna strands stay separate during replication they provide energy for the replication process

Explanation:

Complementary base - pairing in DNA replication follows the rules (A - T, G - C), ensuring that the new DNA molecule has the same genetic information as the original. While it helps maintain accuracy and reduce mutations, its primary role is to make an exact copy. DNA strands separate due to enzymes like helicase, and energy for replication comes from nucleotides with phosphate groups.

Answer:

They ensure that each new DNA molecule is an exact copy of the original.
