NEET 2024 Botany DNA Replication MCQ Question
Which of the following statement is correct regarding the process of replication in E.coli?
(1) The DNA dependent DNA polymerase catalyses polymerization in 5'→3' as well as 3'→5' direction.
(2) The DNA dependent DNA polymerase catalyses polymerization in 5'→3' direction.
(3) The DNA dependent DNA polymerase catalyses polymerization in one direction that is 3'→5'.
(4) The DNA dependent RNA polymerase catalyses polymerization in one direction, that is 5'→3'.
The DNA dependent DNA polymerase catalyses polymerization in 5'→3' as well as 3'→5' direction.
The DNA dependent DNA polymerase catalyses polymerization in 5'→3' direction.
The DNA dependent DNA polymerase catalyses polymerization in one direction that is 3'→5'.
The DNA dependent RNA polymerase catalyses polymerization in one direction, that is 5'→3'.
Correct Answer
Detailed Explanation
In E.coli, the DNA dependent DNA polymerase catalyzes polymerization only in the 5' to 3' direction. This is a fundamental property of DNA polymerases.
