alleryRibosomes in eukaryotic cytoplasm are of which type?
A100S type
B70S type
C80S type
D55S type
Answer & Solution
Correct answer: C. 80S type
Eukaryotic cytoplasmic ribosomes are 80S (60S large + 40S small subunits).
Prokaryotic ribosomes are 70S (50S + 30S).
Mitochondrial and chloroplast ribosomes are 70S — an evolutionary echo of the endosymbiont theory.
