(7 cards)
1
Q
Helicase
A
Breaks hydrogen Bonds (splitting dna into bubble)
2
Q
Primase
A
Adds RNA primer to origin of replication, and provide 3’’-OH for lagging strand allowing nucleotide to attach
3
Q
DNA Polymerase III (Function and specific location)
A
Replicates Leading strand by adding nucleotides (attaching to 3’’-OH)
4
Q
DNA polymerase I
A
Removes RNA primer, replaces the gap with DNA nucleotides
