DNA replication Protiens

Question 1

What is the first protiens that are used?

Answer 1

Helicase, single strand binding protiens, and DNA topoisomerase(gyraise)

Question 2

What is the second protien?

Answer 2

Primase

Question 3

What is the third protien?

Answer 3

DNA polymerase 3

Question 4

What is the fourth protien?

Answer 4

DNA polymerase 1

Question 5

What is the fifth protien?

Answer 5

DNA ligase

Question 6

What does Helicase do?

Answer 6

Unwinds the DNA by breaking the hydrogen bonds between the nitrogenous base pairs

Question 7

What does DNA topoisomerase do?

Answer 7

Prevents coiling ahead of the replication fork. Open dna strands to allow other dna to pass and then rejoins it

Question 8

What does single strand binding protiens do?

Answer 8

Coat the single strands of dna near the replication fork to prevent the single stranded dna from winding back into a double helix

Question 9

What does primase do?

Answer 9

Adds RNA primer 5-10 enzymes long. Primes the DNA synthase. Is the complementary strand
