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 some RNA (called ribosomal RNA) and protein. They are found in both eukaryotic and prokaryotic cells. In prokaryotes, 70 s ribosomes and in eukaryotes, \(80 S\) ribosomes are found where kS' denotes Svedberg unit. They do not have any DNA.
