Question

Choose the incorrect statement:

• A. Replication fork is small opening of DNA
• B. DNA polymerase synthesizes in 3′→5′ direction
• C. 3′→5′ strand is leading strand
• D. DNA polymerase synthesizes 5′→3′

Hint:

All DNA synthesis happens 5′→3′, on a 3′→5′ template.

Answer 1

The Correct Option is B

- DNA polymerase adds nucleotides in 5′→3′ direction, always.
- Template may be 3′→5′, but synthesis happens in 5′→3′.
- Hence, option (2) is incorrect.
