NEET Previous Year Question
Which is the "Only enzyme" that has "Capability" to catalyse Initiation, Elongation and Termination in the process of transcription in prokaryotes?
Topic: NEET PYQ
Answer: A. Full step-by-step solution below.
- ADNA dependent RNA polymerase
- BDNA Ligase
- CDNase
- DDNA dependent DNA polymerase
Correct answer: A
Solution
(a) In prokaryotes, single DNA-dependent RNA polymerase catalyses initiation, elongation and termination in the process of transcription.DNA ligase facilitates the joining of the fragments of DNA. DNase is an endonuclease enzyme which catalyses the breakdown of single- or double stranded DNA.
DNA dependent RNA polymerase cayalyses polymerization of DNA during replication of DNA.
