RNA is synthesised in which direction, and by which enzyme?
A5' to 3', DNA polymerase
B3' to 5', DNA ligase
C5' to 3', RNA polymerase
D3' to 5', RNA polymerase
Answer & Solution
Correct answer: C. 5' to 3', RNA polymerase
1. Synthesis has both a direction and a dedicated enzyme.
2. RNA is synthesized in its 5' to 3' direction.
3. The enzyme responsible is RNA polymerase.
4. DNA polymerase and ligase act on DNA rather than RNA.
