From the statements given below choose the correct option :

A. The eukaryotic ribosomes are 80S and prokaryotic ribosomes are 70S.

B. Each ribosome has two sub-units.

C. The two sub-units of 80S ribosome are 60S and 40S while that of 70S are 50S and 30S.

D. The two sub-units of 80S ribosome are 60S and 20S and that of 70S are 50S and 20S.

E. The two sub-units of 80S are 60S and 30S and that of 70S are 50S and 30S.

1. A, B, C are true

2. A, B, D are true

3. A, B, E are true

4. B, D, E are true

Best answer

Answer: 1. A, B, C are true

Key idea: Eukaryotic ribosomes are 80S, made of 60S and 40S subunits. Prokaryotic ribosomes are 70S, made of 50S and 30S subunits.

A, B and C are true. D and E give wrong subunit sizes (20S and 30S for the 80S ribosome). So A, B, C.
