Which of the Following is a Characteristic of Rho (ρ)Factor

Question

Which of the following is a characteristic of rho (ρ)factor?
A)It winds transcript and template to free nascent RNA.
B)It recognizes and binds U-rich regions of RNA transcripts.
C)Its binding regions must be ribosome free.
D)It advances in the 3'→5' direction to the transcription bubble.

Accepted Answer

Rho factor is a helicase that terminates transcription by binding to RNA at specific sites that are free of ribosomes, allowing it to catch up to the RNA polymerase and release the nascent RNA.
