What is the process called in eukaryotes where replication of DNA takes place?

Options

  1. Aorigin of replication
  2. Breplication fork
  3. CS-phase of the cell-cycle
  4. Dnone of the above

Correct answer

C. S-phase of the cell-cycle

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
