dna replication - ib bio

l

A

stage one

helicase attaches and unwinds the double helix and seperates the two strands by breaking hydrogen bonds

stage two

DNA polymerase links nucleotides together to form new strands (using pre-existing strands as templates), and complementary base-pairing causes the new strand to be the same as the old

stage three

the daughter DNA molecules each rewind into a double helix
