From the statements given below choose the correct option :
- A, B, E are true
- B, D, E are true
- A, B, C are true
- A, B, D are true
Answer
(3) A, B, C are true
Solution
Eukaryotic ribosomes are 80S and prokaryotic ribosomes are 70S (A true). Each ribosome has two sub-units (B true).
80S ribosome = 60S + 40S; 70S ribosome = 50S + 30S (C true; D and E false).
Hence, A, B and C are true.
Answer: (3)
