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 strat and stop codons.

D

Text Solution

Verified by Experts

The correct Answer is:
A
`**" "`The cellular factory responsible for synthesis proteins is the ribsome. 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.
