Question

Subunits in prokaryotic ribosomes are

• A. 60 S, 40 S
• B. 50 S, 30 S
• C. 40 S, 30 S
• D. 50 S, 20 S

Answer 1

The correct option is B 50 S, 30 S

Prokaryotic ribosome is of 70 S type, which consists of two sub units, a small 30 S subunit and a large 50 S subunit. Eukaryotic ribosome is of 80 S type. It consists of two subunits, a small 40 S subunit and a large 60 S subunit.
