DNA Replication

Question 1

DNA Ligase

Answer 1

an enzyme that catalyzes the formation of a phosphodiester bond between 2 DNA strands as well as between the okazaki fragment

Question 2

DNA polymerase 3

Answer 2

a prokaryotic replication enzyme that builds new DNA strands from nucleotides

Question 3

DNA primase

Answer 3

an enzyme that synthesizes short RNA called primers

Question 4

Helicase

Answer 4

a replication enzyme that separates and unwinds the DNA strand

Question 5

Lagging strand

Answer 5

The DNA strand that is copied in the direction toward the replication fork

Question 6

Okazaki Fragment

Answer 6

The piece of new DNA on the lagging strand

Question 7

Replication Fork

Answer 7

The point of separation of the 2 parent DNA strands during replication

Question 8

Single strand binding proteins

Answer 8

a replication enzyme that prevents parent DNA strands from rejoining each other once they have been separated by helicase

Question 9

Topoisomerase

Answer 9

A class of enzymes that relieve tension caused by the unwinding of parent DNA
