Question

What happens when the polymerase enzyme reaches the terminator region during transcription?

(a) The nascent RNA falls off

(b) The nascent DNA falls off

(c) The nascent protein falls off

(d) The nascent enzyme falls off

This question was posed to me by my college director while I was bunking the class.

Asked question is from Types of RNA and Process of Transcription in Prokaryotes topic in division Molecular Basis of Inheritance of Biology – Class 12

Answer 1

Correct choice is (a) The nascent RNA falls off

To explain I would say: During the termination stage of transcription process, the nascent RNA falls off. This is observed when the polymerase enzyme reaches the terminator region. Following this, the RNA polymerase enzyme also falls off.
