Question

directions: below are the 3 steps in dna replication. follow the directions for each step and then answer the questions below. what is happening to the dna molecule in the figure? what happens to the dna molecule during the second step of dna replication? what happens during the third step of dna replication?

Explanation:

In the first step, the DNA double - helix is unwinding. Enzymes break the hydrogen bonds between base pairs to separate the two strands. In the second step, free nucleotides are pairing with the separated DNA strands according to base - pairing rules (A with T, C with G). In the third step, two complete DNA molecules are formed, each consisting of one original strand and one newly - synthesized strand.

Answer:

What is happening to the DNA molecule in the figure? - The DNA double - helix is unwinding.
What happens to the DNA molecule during the second step of DNA replication? - Free nucleotides pair with the separated strands.
What happens during the third step of DNA replication? - Two complete DNA molecules are formed, each with one old and one new strand.
