Question

What is the function of primase in DNA replication?

• A. To synthesize RNA primers
• B. To unwind the DNA helix
• C. To join Okazaki fragments
• D. To remove RNA primers

Answer 1

Answer:

A. To synthesize RNA primers

Primase is an enzyme that synthesizes RNA primers, which are short RNA sequences that initiate DNA replication. Primase is essential for DNA synthesis because DNA polymerases can only add nucleotides to an existing DNA strand.
