DNA Replication

Question 1

Stage 1
(Helicase)

Answer 1

Double helix untwists because of the helicase enzyme

Question 2

Stage 2

H bonds

Answer 2

DNA strands separate because hydrogen bonds have broken between bases

Question 3

Stage 3

Template

Answer 3

Both strands are a Template (things being copied)

Question 4

Stage 4

Complementary

Answer 4

Nucleotides join onto the exposed bases forming complementary pairs (A&T and C&G) joined by hydrogen bonds

Question 5

Stage 5

Phosphodiester

Answer 5

DNA polymerase then joins Nucleotides together with Phosphodiester bonds, forming the sugar phosphate backbone.

Question 6

Stage 6

Semi conservative

Answer 6

This is semi conservative replication because each of the DNA molecules consist of 1 old strand and 1 new strand
