5.2 DNA Replication

Question 1

Stages of DNA Replication (in order)

Answer 1

Helicase
Primase
DNA Polymerase 3
DNA Polymerase 1
Ligase

Question 2

What does each of the stages accomplish

Answer 2

Helicase: Unzips the DNA
Primase: Makes the primer
DNA Polymerase 3: The main DNA builder
DNA Polymerase 1: Edits and repairs DNA
Ligase: Joins the fragments.

Question 3

What are the two main types of primes in a nucleotide

Answer 3

3’ and 5’

Question 4

What are the two types of strands and which direction do they go

Answer 4

Leading (5’ to 3’)
Lagging (3’ to 5’)

Question 5

What does each of the strands do

Answer 5

Leading: Continuous synthesis
Lagging: Copied backwards into sections called Okazaki Fragments.
