Question

What distinguishes eukaryotic ribosomes from prokaryotic ones?
Options
A Eukaryotic ribosomes are located outside the cell
B Prokaryotic ribosomes produce DNA
C Eukaryotic ribosomes are larger and structurally distinct
Correct Answer
D Prokaryotic ribosomes are only found in the nucleus
Correct Answer

Option C is the correct answer.

Detailed Explanation

Eukaryotic ribosomes are larger (80S, composed of 60S and 40S subunits) than prokaryotic ribosomes (70S, composed of 50S and 30S subunits). They also differ in some RNA and protein components, which is the basis for certain antibiotics that target bacterial ribosomes selectively.

Hint

The 'S' value refers to size and sedimentation rate.
