Question

The primary job of rRNA in the smaller 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 binding of mRNA to the ribosome
• D. Facilitate the transfer of peptidyl bonds between amino acids

Answer 1

The correct option is C Facilitate the binding of mRNA to the ribosome

rRNA does not have a role in providing any genetic information during protein synthesis; in the smaller ribosomal subunit, rRNA has certain specialised sites which facilitate the binding of mRNA to the ribosome to initiate the process of translation.
