Select the correct statement regarding protein synthesis.

When the small subunit of the ribosome encounters an $mRNA$ the process of translation begins.

Peptidase catalyses the formation of peptide bond.

$UTRs$ are present between the start codon and stop codon.

At the end of translation, the release factor binds to the initiation codon.

Solution

Peptidase catalyses the breaking of peptide bond. The $UTRs$ are present at both $5 \phi$-end (before start codon) and $3'-end$ (after stop codon). At the end of translation release factor binds to the stop codon, terminating translation and releasing the complete polypeptide from the ribosome.

Assertion : Replication and transcription occur in the nucleus but translation takes place in the cytoplasm.

Reason : $mRNA$ is transferred from the nucleus into cytoplasm where ribosomes and amino acids are available for protein synthesis.
