Question

Select the incorrect statement about prokaryotic ribosomes
(a) 50S and 30S subunits unite to form 70S ribosomes
(b) Polysome / polyribosome consists of many ribosomes only
(c) Ribosome is the site of protein synthesis
td Polysome indicate the synthesis of identical polypeptide
in multiple copies​

Answer 1

Answer:

b)

Explanation:

polysomes consits of many ribosomes only

this incorrect becoz polysomes consits of mRNA and ribosomes

Answer 2

Option (B) is Right Answer

Explanation:

  (b) Polysome / polyribosome consists of many ribosomes only

• The most various intracellular structure is the ribosome which is the site of protein synthesis in every single living organisms
• All prokaryotes have 70S ribosomes while eukaryotes contain bigger 80S ribosomes in their cytosol
• The 70S ribosome is comprised of a 50S and 30S subunits  
• The two eukaryotes and prokaryotes contain enormous RNA/protein structures called ribosomes
