Cards

Term
Helicase
Definition
Unwinds parental double helix at replication forks
Term
Single-strand binding protein
Definition
Binds to and stabilizes single-stranded DNA until it can be used as a template
Term
Topoisomerase
Definition
Corrects "over-winding" ahead of replication forks by breaking, swiveling, and rejoining DNA strands
Term
Primase
Definition
Function for leading strand: Synthesizes a single RNA primer at the 5' end of the leading strand.

Function for lagging strand: Synthesizes an RNA primer at the 5' end of each Okazaki fragment
Term
DNA polymerase I
Definition
Function for leading strand: Removes primer from the 5' end of leading strand and replaces it with DNA, adding on to the adjacent 3' end

Function for lagging strand: REmoves the primer from the 5' end of each fragment and replaces it with DNA, adding on to the 3' end of the adjacent fragment
Term
DNA polymerase III
Definition
Function for leading strand: Continuously synthesizes the leading strand, adding onto the primer.

Function for lagging strand: Elongates each Okazaki fragment, adding on to its primer
