Chain termination occurs,in vivo,when:
A) RNA Pol gets to the end of the DNA.
B) The factor called rho (r) binds to the DNA.
C) A hairpin loop forms in the template.
D) Either a hairpin loop forms or rho (r) is involved.

Question

Quizplus · Accepted Answer

Chain termination can occur in vivo by either the formation of a hairpin loop in the template (which causes RNA polymerase to pause or stop) or when the protein factor rho (r) binds to the RNA and causes it to dissociate from the DNA. Thus, the best choice is D as it includes both possibilities.
