Termination of RNA Synthesis is Ultimately Determined By

Question

Termination of RNA synthesis is ultimately determined by
A) exhaustion of RNA polymerase activity.
B) special protein factors.
C) terminases.
D) specific nucleotide sequences on the template strand.

Accepted Answer

Termination of RNA synthesis is determined by specific nucleotide sequences on the template strand. At these termination sites, the newly synthesized RNA transcript is released from the RNA polymerase. These termination sequences are recognized by specific protein factors that cause the RNA polymerase to pause and release the transcript.
