Question

Q. What is true about ribosomes?
A The prokaryotic ribosomes are \(80 S\), where 'S' stands for sedimentation coefficient
B) These are composed of ribonucleic acid and proteins
c) These are found only in eukaryotic cells
D These are self-splicing introns of some RNAs

Answer 1

Solution:
Ribosome is a small spherical body within a living cell that is the site of protein synthesis. Ribosomes consist of two subunits, one large and one small, each of which comprises a type of RNA
(called ribosomal RNA) and protein. They are found in both eukaryotic and prokaryotic cells. In prokaryotes \(70 \mathrm{~S}\) ribosomes and in eukaryotes \(80 \mathrm{~S}\) ribosomes are found where ' \(\mathrm{S}\) ' denotes
Svedberg Unit.
