Question

After DNA is unzipped, what is the next step in DNA replication?
A. Messenger RNA forms along the exposed DNA bases.
B. A chromosome with two identical strands of DNA is formed.
C. Nitrogen bases pair up with the DNA strands.
D. Ribosomes attach to DNA and move along the strand.

Answer 1

Answer:

Step 2: Primer Binding

The leading strand is the simplest to replicate. Once the DNA strands have been separated, a short piece of RNA called a primer binds to the 3' end of the strand. The primer always binds as the starting point for replication. Primers are generated by the enzyme DNA primase.
