DNA replication Flashcards
1
Q
helicase
A
unwinds DNA helix at replication fork
2
Q
DNA polymerase III
A
synthesizes new DNA strand by adding nucleotides to an RNA primer
3
Q
single stranded binding protein
A
binds & stabilizes single-stranded DNA until it’s used as a template
4
Q
topoisomerase
A
relaxes supercoiled DNA ahead of the replication fork so that replication may proceed
5
Q
primase
A
begins synthesis of RNA primer
6
Q
DNA polymerase I
A
degrades RNA primer by replacing the strand
7
Q
DNA ligase
A
joins (ligates) Okazaki fragments into daughter strands
