Question

1. ccc analyze structure and function dna replication begins when the double helix untwists and breaks in half between the nitrogen bases. what are the next two steps in the process of dna replication? 202 genes and heredity

Explanation:

After the DNA double - helix untwists and separates, free nucleotides pair with the exposed bases on each of the separated strands according to base - pairing rules (A with T, C with G). Then, an enzyme called DNA polymerase links the nucleotides together to form a new strand complementary to each of the original strands.

Answer:

1. Free nucleotides pair with exposed bases.
2. DNA polymerase links nucleotides to form new strands.
