Question

The primary job of rRNA in the larger subunit of ribosome is to

• A. Provide some part of the genetic information
• B. Facilitate the binding of tRNA to the ribosome
• C. Facilitate the transfer of peptidyl bonds between amino acids
• D. Keep both the units of the ribosome bound together

Answer 1

The correct option is C Facilitate the transfer of peptidyl bonds between amino acids

rRNA in the larger ribosomal subunit acts as an enzyme and catalyses the transfer of peptidyl bonds between amino acids during the formation of the polypeptide chain. This is the reason ribosomes are also known as ribozymes.
