Read each question carefully and answer to the best of your ability. Show all your work where applicable.

1. Which enzyme is responsible for unwinding the DNA double helix during replication?

a

DNA Polymerase

b

Ligase

c

Helicase

d

Primase

2. What is the role of DNA ligase in DNA replication?

a

Synthesizes new DNA strands

b

Unwinds the DNA double helix

c

Joins Okazaki fragments

d

Adds RNA primers

3. DNA replication is a   process, meaning each new DNA molecule consists of one original strand and one newly synthesized strand.

4. The enzyme   adds complementary nucleotides to the growing DNA strand.

5. Short segments of DNA synthesized on the lagging strand are called   fragments.

6. Describe the function of DNA primase in DNA replication.

7. The leading strand is synthesized continuously, while the lagging strand is synthesized discontinuously.

T

True

F

False
