What are the 3 steps of DNA replication?
1) DNA polymerase unwinds the DNA helix
2) Helicase proof reads the strands
3) 3 Helices are made
1) Helicase unwinds & unzips the DNA helix
2) DNA polymerase adds on free floating nucleotides
3) DNA polymerase proof reads the molecule
1) Unzipperase unwinds and unzips the DNA double helix
2) Ligase proof reads the double helix
3) DNA polymerase adds of free floating nucleotides
