2
Q
Step 1
A
Double helix is unwound by an EMZYNE
Hydrogen bonds are unzipped
3
Q
What is a primer
A
Short complementary strand of DNA
4
Q
What does the ligase enzyme do
A
Join the replicated fragments and the lagging strand together
5
Q
Why is DNA replication important
A
Because it ensures that identical copies of the genetic information of a species are passed on from cell to cell ,from generation to generation
6
Q
DNA polymerase
A
Bonds nucleotides into backbone
7
Q

A
Joins fragments
8
Q
Step2
