Q
steps
A
- DNA Helicase is an enzyme that unzips and breaks hydrogen bonds in base pairs
- SIngle strand Binding proteins SSB- will attach to unzipped base pairs, so that they don’t bond again
- RNA primase-Enzyme primer that directs DNA polymerace wher to go
5DNA polymerace III-builds new nucliotides new complmentary strands move toward the fork - DNA polymerace I- enxyme builds new strand, moves away from fork. proof reading ability
- DNA ligase glues the ozaki fragments together.
