Question

which enzyme is responsible for adding new nucleotides during dna replication?
○ a. ligase
○ b. primase
○ c. dna polymerase
○ d. helicase

Explanation:

• Ligase: Joins DNA fragments, not adding nucleotides.
• Primase: Synthesizes RNA primers, not adding DNA nucleotides.
• DNA polymerase: Catalyzes the addition of new nucleotides to the growing DNA strand during replication.
• Helicase: Unwinds the DNA double - helix, not adding nucleotides.

Answer:

C. DNA polymerase
