DNA replication Flashcards
1
Q
DNA Gyrase
A
relaxes and unwinds the DNA spiral
2
Q
DNA Helicase
A
- recognizes the sequence of bases and attaches at the origin of the replication site.
- breaks down the hydrogen bonds
- creates a replication fork
3
Q
SSBs
A
attaches to each strand to prevent the bonds from reforming and keeps the strands apart
4
Q
RNA Primase
A
adds RNA primer to the replication site
5
Q
RNA Primer
A
short segment of base pairs that acts as an indicator site
6
Q
Okazaki Fragments
A
short DNA nucleotide fragments added by RNA primer, later joined by DNA Ligase to form the lagging strand
7
Q
DNA Polymerase lll
A
adds free floating nucleotides to the leading strand using the DNA Primers sites
8
Q
DNA Polymerase l
A
moves in and replaces the RNA primer, leaving a small gap
9
Q
DNA Ligase
A
seals the gap
10
Q
DNA Polymerase ll
A
checks for mistakes
