Question

The function of polysome in bacterial cell is to

• A. Translate the mRNA into protein
• B. Store reserve food materials
• C. synthesize pigments
• D. help in buoyancy

Answer 1

The correct option is A Translate the mRNA into protein

Polysomes are ensembles of two or more consecutive ribosomes that translate mRNA into proteins. Adjacent ribosomes can affect the frequency with which a new ribosome is loaded into the polysome. When the translating ribosome has cleared the start codon, the consecutive ribosome can rapidly move to the translation start. Recruitment to the standby site is a mechanism to increase polysome density and to regulate the efficiency of translation in polysomes. Hence the correct answer is (A)
