DNA Replication Flashcards
1
Q
Stage 1 (Helicase)
A
Double helix untwists because of the helicase enzyme
2
Q
Stage 2
H bonds
A
DNA strands separate because hydrogen bonds have broken between bases
3
Q
Stage 3
Template
A
Both strands are a Template (things being copied)
4
Q
Stage 4
Complementary
A
Nucleotides join onto the exposed bases forming complementary pairs (A&T and C&G) joined by hydrogen bonds
5
Q
Stage 5
Phosphodiester
A
DNA polymerase then joins Nucleotides together with Phosphodiester bonds, forming the sugar phosphate backbone.
6
Q
Stage 6
Semi conservative
A
This is semi conservative replication because each of the DNA molecules consist of 1 old strand and 1 new strand
