Question

Which is the "only enzyme" that has the "capability" to catalyse initiation, elongation and termination in the process of transcription in prokaryotes?

• A. DNA-dependent DNA polymerase
• B. DNA ligase
• C. DNA-dependent RNA polymerase
• D. DNase

Answer 1

Answer:

C. DNA-dependent RNA polymerase

DNA-dependent RNA polymerase is an essential enzyme in the transcription of the transcription systems of prokaryotes and eukaryotes as well as viral cytoplasmic DNA. The process by which the information is copied from a DNA strand to a messenger mRNA is known as transcription. This process is carried out with the help of the enzyme RNA polymerase. There are three stages in the process of transcription in prokaryotes. They are initiation, elongation, and termination
