Which of the following statement is correct regarding the process of replication in E. coli?

  1. The DNA dependent DNA polymerase catalyses polymerization in one direction that is 3' 5'
  2. The DNA dependent RNA polymerase catalyses polymerization in one direction, that is 5' 3'
  3. The DNA dependent DNA polymerase catalyses polymerization in 5' 3' as well as 3' 5' direction
  4. The DNA dependent DNA polymerase catalyses polymerization in 5' 3' direction

Answer

(4) The DNA dependent DNA polymerase catalyses polymerization in 5' 3' direction

Solution

In replication the main enzyme is DNA dependent DNA polymerase (RNA polymerase is used in transcription).

It catalyses polymerisation only in one direction, 5' 3'; hence replication is continuous on the template with polarity 3' 5' and discontinuous on the other strand.

Answer: (4)
