Question

Quizplus · Accepted Answer

Ribosomes are composed of two subunits, one large and one small, that are made up of both RNA and protein molecules. The RNA portion of ribosomes is called ribosomal RNA (rRNA). Therefore, choice B, RNA and proteins, is the best choice. Choices A, C, D, and E are incorrect because DNA and sugars do not make up ribosomes, and nucleosomes are not a component of ribosomes.
