Flashcards in DNA Replication Deck (8):
1

Leading Strand

Continuous Replication
-this strand is unzipping 3 to 5 prime direction

2

Lagging Strand

Discontinuous Replication
-this strand is unzipping 5 to 3 prime direction

3

DNA Replication

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

Helicase

unwinds and separates the DNA strands

5

Primase

creates the RNA primer

6

DNA Polymerase III

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

Polymerase I

replaces RNA primers with DNA

8

Ligase

attaches the okazaki fragments together
