Options

  1. AA - 1, B - 4, C - 3, D - 2
  2. BA - 3, B - 1, C - 4, D - 2
  3. CA - 2, B - 3, C - 1, D - 4
  4. DA - 4, B - 3, C - 2, D - 1

Correct answer

D. A - 4, B - 3, C - 2, D - 1

Step-by-step solution

A plasmid acts as a vector, DNA ligase joins DNA molecules, restriction enzymes are molecular scissors, and the origin of replication enables DNA to replicate.
