DNA Replication Flashcards
1
Q
Leading Strand
A
Continuous Replication
-this strand is unzipping 3 to 5 prime direction
2
Q
Lagging Strand
A
Discontinuous Replication
-this strand is unzipping 5 to 3 prime direction
3
Q
DNA Replication
A
The DNA is unzipped in the middle of the double helix
- it can only be read 3 to 5 prime
- it is written 5 to 3 prime
4
Q
Helicase
A
unwinds and separates the DNA strands
5
Q
Primase
A
creates the RNA primer
6
Q
DNA Polymerase III
A
lays down the new DNA strand
or
in the lagging strand it lays down the okazaki fragments
-it needs primase to work . It has to know where to lay down the new DNA nucleotides.
7
Q
Polymerase I
A
replaces RNA primers with DNA
8
Q
Ligase
A
attaches the okazaki fragments together
