DNA Replication
In which of the following directions does DNA replicate?
7' to 5'
5' to 7'
3' to 7'
5' to 3'
What is the first step in DNA replication?
Helicase "unzips" the DNA
Okazaki fragments are formed
DNA replicase initiates replication
An ATP molecule binds to the 3' end of the DNA
What is the purpose of the RNA primer?
To inhibit replication of DNA
To replicate DNA from 3' to 5'
To expose the DNA to helicase
Serves as a guide for DNA polymerase.
What is the function of DNA polymerase?
To provide a replication protection for the DNA
To initiate the action of helicase.
To help put Okazaki fragments in place.
To construct a new strand of DNA by binding the nucleotides together.
DNA replication is
Conservative
Non-conservative
Semi-conservative
Selectively-conservative
