Question

Ribosomal subunits are large complexes composed of numerous polypeptides and at least one rRNA molecule. Which subunits include three rRNA molecules?

A) Bacterial large subunits
B) Prokaryotic small subunits
C) Eukaryotic large subunits
D) Eukaryotic small subunits

Answer 1

Eukaryotic large subunits

Step-by-step explanation:

Eukaryotic large subunits include three rRNA molecules which are known as 5S, 5.8S and 28S in humans and other members of the Mammal class. Other ribosomes have at least one large and one small rRNA, and when they combine with ribosomal proteins they constitute the large and small subunits of the ribosomes, which in bacteria are known as 50S and 30S.
