Unit 4 DNA replication phase 1

Question 1

Origins of replication

Answer 1

-sequence of nucleotides that can start replication
-specific protien gotta read them to start

-as replication begins a replication bubble forms

Replication fork forms and new strand is synthesized r all sides

Question 2

Enzymes

1. Helicase:
2. SSB:
3. Topoisomerase:

Answer 2

1. Helicase: Seperates base pairs by breaking hydrogen bonds
2. SSB: keeps hydrogen bonds from reforming and keeping single strand DNA stable
3. Topoisomerase: Relieves tention by making tiny cuts so it doesn’t coil back on its self
