Text Solution

Verified by Experts
The correct answer is:
B

When the smaller subunit of the ribosome encounters an mRNA, the process of translation begins. The UTRs are present at both -end (before start codon) and at -end (after stop codon). The ribosome also acts as a catalyst (23 S rRNA in bacteria is the enzyme-ribozyme) for the formation of peptide bond.
