DNA Replication Flashcards
(6 cards)
1
Q
Name two requirements for DNA Replication.
A
- Original DNA template
OR
- Free DNA nucleotides
OR
- DNA polymerase
OR
- Primers
2
Q
What happens during stage 1 of replication?
A
The double helix molecule is unwound and unzipped. Special molecules break the hydrogen bonds between the bases
3
Q
During stage 2, what way does DNA polymerase add free nucleotides?
A
In a 5’ to 3’ direction
4
Q
Name the enzyme involved in DNA replication.
A
DNA polymerase
5
Q
How are DNA fragments sealed?
A
By the enzyme ligase
6
Q
What happens during stage three of replication?
A
The two new strands twist together and form a double strand. Each is identical to the original strand
