1
New cards
DNA Polymerase I
Removes RNA primer and replaces it with newly synthesized DNA
2
New cards
DNA Polymerase III
Main enzyme that adds nucleotides in the 5’-3’ direction
3
New cards
Helicase
Opens the DNA helix by breaking hydrogen bonds between the nitrogenous bases
4
New cards
Ligase
Seals the gaps between the Okazaki fragments to create one continuous DNA strand
5
New cards
Primase
Synthesizes RNA primers neded to start replication
6
New cards
Sliding Clamp
Helps to hold the DNA polymerase in place when nucleotides are being added
7
New cards
Topoisomerase
Helps relieve the strain on DNA when unwinding by causing breaks, and then resealing the DNA
8
New cards
Single-strand binding proteins (SSB)
Binds to single-stranded DNA to prevent DNA from rewinding back
