Question

Which of the following will not result in termination of transcription?

		Dissociation of RNA polymerase from the template when termination site is recognized
		Presence of a UUU motif near the 3' end of the transcript
		Phosphorylation of RNA polymerase at the CTD region
		Binding of rho helicase to CA-rich sequences

Answer 1

Presence of a UUU motif near the 3' end of the transcript will not result in the termination of transcription.

The termination of transcription is done by dissociation of RNA polymerase (rho factor) from template when termination site is recognised, phosphorylation of RNA polymerase at the CTD region (The CTD functions to help couple transcription and processing of the nascent RNA and also plays roles in transcription elongation and termination), binding of rho helicase to CA-rich sequences and its move to the end and terminate transcription.
