Which of the following represents the correct order of events as they occur in the
process of DNA replication?
Hint: Not all steps of replication are indicated in every choice.
Primase synthesizes RNA primer, pol III synthesizes lagging and leading strands,
and helicase opens helix.
Helicase opens helix, pol III synthesizes RNA primer of leading strand, and pol I
excises primer and fills gap.
Helicase opens helix, pol III elongates primer and synthesizes leading and lagging
strands, and DNA ligase links fragments of DNA.
Primase synthesizes primer, pol I excises primer, and pol III elongates primer and
synthesizes leading and lagging strands.
