Ribosome sizes are
A70S in eukaryotes, 80S in prokaryotes
B80S in both
C70S in both
D70S in prokaryotes, 80S in eukaryotes
Answer & Solution
Correct answer: D. 70S in prokaryotes, 80S in eukaryotes
Prokaryotic ribosomes are 70S (50S + 30S subunits), eukaryotic ribosomes are 80S (60S + 40S). Mitochondrial and chloroplast ribosomes are 70S, hinting at their bacterial origin (endosymbiotic theory).
