Select one which is not true for ribosomes.

Options

A. Made of two subunits
B. From polysome
C. May attach to mRNA
D. Have no role in protein synthesis

Answer

D

Explanation

Ribosomes are cell organelles that are formed of two subunits. They are capable of forming polyribosomes during which many ribosomes are attached to mRNA. The purpose of ribosomes moving on mRNA is to synthesise proteins i.e, translation. Indeed, ribosomes have a very direct role in protein synthesis.
