Question

The correct order of events for synthesis of the lagging strand is:

• A. Primase adds RNA primer, DNA polymerase III creates a stretch, DNA polymerase I removes the primer, and ligase seals the gaps.
• B. Primase adds primer, DNA polymerase I removes the primer, DNA polymerase extends the segment, and ligase seals the gap.
• C. Ligase adds bases to the primase, the primase generates the polymerase 1, polymerase III adds to the stretch, helicase winds the DNA
• D. Helicase unwinds the DNA, primase creates a primer, DNA polymerase I elongates the stretch, DNA polymerase III removes the primer, and ligase seals the gaps in the DNA

Answer 1

Answer: (A)

Primase adds RNA primer, DNA polymerase III creates a stretch, DNA polymerase I removes the primer, and ligase seals the gaps.
