Ribosome is a molecular machinery, which is located in all living cells. It is formed from proteins and complexes of rRNA ( ribosomal RNA). That is why, it is also called as ribonucleoprotein.
Ribosome serves as the site for protein synthesis. It is primarily divided into two subunits, a larger ribosomal subunit and a smaller ribososmal subunit, which together assist the process of protein formation ( translation).
Thus, the components of ribosomes are RNA and proteins.
