Explanation / Answer
Which best describes the composition of a ribosome?
A ribosome consists of many molecules of RNA in single copy each and many different polypeptide chains.
Ribosome mainly consists two major subunits and they are 1)small ribosomal subunit, which reads the RNA, and 2) the large subunit, which joins amino acids to form a polypeptide chain. Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins. And these molecules of RNA are in single copy each.
