A) 16 RNAs and a variety of proteins.
B) an 80S (30S + 50S) component made of RNA and proteins.
C) 80S subunits along with several RNAs and at least 50 proteins.
D) two subunits made of three RNAs and at least 50 proteins.
E) three subunits containing both RNA and proteins.

Accepted Answer

The typical bacterial ribosome is composed of two subunits - a small subunit made of three RNAs and at least 21 proteins, and a large subunit made of two rRNAs and at least 31 proteins, for a total of three RNAs and at least 52 proteins.
