Question

Select correct statement about protein synthesis.

• A. Translation begins when $mRNA$ attaches to small subunit of ribosome.
• B. Peptidase catalyses formation of peptide bond.
• C. $UTRs$ are present between start and stop codons.
• D. At the end of translation, release factor binds to intiation codon.

Answer 1

Answer: (A)

• The cellular factory responsible for synthesising proteins is the ribosome. The ribosome consists of structural $RNAs$ and about $80$ different proteins.
• In its inactive state, it exists as two subunits; a large subunit and a small subunit.
• When the small subunit encounters an $mRNA$, the process of translation of the $mRNA$ to protein begins
