Replication

unwinds parental double helix at replication forks

binds to and stabilizes single standed Dna until it can be use as a temple

overwinding stain ahead of replication forks by breaking swiveling and rejoining DNA strands

synthesizes RNA 5' end of leading strand and each okazaki Fragment of agging strand

using parental DNA as a temple synthesizes new DNA strand by adding nuceotides to the 3' end of pre existing DNA

Removes RNA nucleotides of primer from 5' end and replaces them with DNA nucleotides

Joins 3' end of DNA that replaces primer to rest of leading strands joins Okazaki fragments

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
