Question

Which of the following types of ribosomes are present in prokaryotic cells?
(a) 80 S
(b) 90 S
(c) 70 S
(d) 60 S

Answer 1

50s for large and 30s for small making it for 80s types of ribosomes are present in prokaryotic cells.

Prokaryotes have those ribosomes that are slightly smaller than eukaryotes which have a total of 60 s for large and 40 s for smaller.

Other than that the structural difference between ribosomes found in the mitochondria and free ribosomes.
