Q
what are RNA primers?
A
short nucleic acid sequence synthesized by RNA polymerase, indicate the starting point of DNA replication

Q
what is a replication fork?
A
The point at which DNA replication is occurring, consisting of a leading and lagging strand
3
Q
what is a helicase?
A
Enzyme responsible for opening up the DNA double helix strands during replication
4
Q
what are single stranded binding proteins?
A
Protein that helps keep the DNA strands unwound during replication
5
