Question

Name an enzyme required for transcription.

Answer 1

RNA Polymerase:

1. RNA polymerase is the main enzyme involved in transcription. It generally uses single-strand DNA to synthesize complementary RNA strands.
2. In prokaryotes, only a single polymerase is required to bind with the DNA strands,
3. The DNA-dependent RNA polymerase also binds to the promoter and catalyzes polymerization in 5’ to 3’ direction on the template strand.
4. Once it reaches the terminator sequence, the process generally terminates and the newly synthesized RNA strand is released.
