What is true about ribosomes? (a) The prokaryotic ribosomes are 80S, 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 selfsplicing introns of some RNAs.
Option B is correct. 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 some RNA (called ribosomal RNA) and protein. They do not have any DNA.
