What is the purpose of vectors in recombinant DNA procedures?

Options

  1. Ato provide the origin of replication
  2. Bto catalyze polymerization
  3. Cto join discontinuously synthesized fragments
  4. Dnone of the above

Correct answer

A. to provide the origin of replication

Step-by-step solution

The DNA polymerases on their own cannot initiate the process of replication. Also the replication does not initiate randomly at any place in DNA. There is a definite region in E. coli DNA where the replication originates. Such regions are termed as origin of replication. It is because of the requirement of the origin of replication that a piece of DNA, if needed to be propagated during recombinant DNA procedures, requires a vector. The vectors provide the origin of replication. Further, not every detail of replicat
