unwinds parental double helix at replication forks
SB/SP
binds to and stabilizes single standed Dna until it can be use as a temple
Topo
overwinding stain ahead of replication forks by breaking swiveling and rejoining DNA strands
Primase
synthesizes RNA 5' end of leading strand and each okazaki Fragment of agging strand
DNA poll III
using parental DNA as a temple synthesizes new DNA strand by adding nuceotides to the 3' end of pre existing DNA
DNA POL I
Removes RNA nucleotides of primer from 5' end and replaces them with DNA nucleotides
DNA LIGASE
Joins 3' end of DNA that replaces primer to rest of leading strands joins Okazaki fragments
okazaki fragment
a short segment of DNA synthesized away from the replication fork on a tmplate strand druring dna replication. Many such segments are joined together to make up the laggind strand of newly synthesized dna
