Question | Answer |
helicase | unwinds parental double helix, unzips down center (starts at sections with A-T's because they have fewer bonds and are broken more easily |
binding proteins | stabilize separated strands, prevents DNA from rezipping (not an enzyme) |
primase | adds short RNA primer strand to template/parental strand |
DNA polymerase | adds DNA nucleotides to build polymer |
exonuclease | removes RNA primer and inserts correct DNA nucleotides |
ligase | joins Okazaki fragments and seals nicks in sugar-phosphate backbone |
quirks of DNA polymerase: | can only add nucleotides of 3-prime end of growing strand), can only add FIRST to RNA |
