1. Which enzyme is responsible for unwinding the DNA double helix during replication?
DNA Polymerase
Ligase
Helicase
Primase
2. What is the role of DNA ligase in DNA replication?

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.
