The combined sizes of prokaryotic and eukaryotic ribosomes are
A) the same.
B) 30S and 50S, respectively.
C) 40S and 60S, respectively.
D) 70S and 80S, respectively.

Question

Quizplus · Accepted Answer

Prokaryotic ribosomes are made up of a 30S small subunit and a 50S large subunit, which combine to form a total size of 70S. Eukaryotic ribosomes, on the other hand, consist of a 40S small subunit and a 60S large subunit, which combine to form a total size of 80S.
