The most important feature of a plasmid to serve as a vector in gene cloning experiment is:

Options

  1. AOrigin of replication (ori)
  2. BPresence of a selectable marker
  3. CPresence of sites for restriction endonuclease
  4. DIts size

Correct answer

A. Origin of replication (ori)

Step-by-step solution

Origin of replication (ori) is a sequence from where replication starts and any piece of DNA when linked to this sequence can be made to replicate within the host cells.
