Question

With the help of which of the following proteins does the ribosome recognize the stop codon?

• A. Cleavage Factors (CF)
• B. Elimination Factors (EF)
• C. Termination Factors (TF)
• D. Release Factors (RF)

Answer 1

Answer:

D. Release Factors (RF)

• The ribosome recognizes the stop codon with the help of Release Factors (RF).

• They have shapes mimicking that of tRNA.

• In E. coli there are three RFs: RF 1, RF 2, and RF 3.
