BIO 120- DNA replication

parent DNA

The original DNA molecule in DNA replication

Daughter DNA

The new DNA molecule in DNA replication

helicase

DNA replciation step 1: unwinds a portion of the DNA double helix and makes it single stranded 

single stranded binding proteins

DNA replication step 2: binds to the single stranded DNA to keep the two strands apart 

topoisomerase

DNA Replication step 3: breaks, swivels, and rejoins the parental DNA ahead of the replication fork to relieve strain caused by the unwinding of DNA by helicase 

DNA polymerase

DNA replication step 4: catalyze replication

deoxyribose; ribose
