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.
Choose the correct answer from the options given below:
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.
Choose the correct answer from the options given below:
A
A, B, C are true
B
A, B, D are true
C
A, B, E are true
D
B, D, E are true
Explanation
Statements A, B, and C are true: 80S = 60S + 40S, 70S = 50S + 30S.
Detailed Solution
Ribosomes consist of large and small subunits. Eukaryotic 80S ribosomes are made of 60S and 40S subunits, whereas prokaryotic 70S ribosomes consist of 50S and 30S subunits. Thus A, B, and C are correct.
