Question

Which of the following proteins bind to the ribosome and causes the dissociation of the two ribosomal subunits from mRNA?

• A. RF 1
• B. RF 2
• C. RF 3
• D. RRF

D. RRF

• RRF binds to the ribosome on the empty site.

• A reaction cascade follows this binding and ultimately results in the release of two ribosomal subunits from mRNA. RRF is Ribosome Release Factor.
