A ribosome is composed of two parts known as the large and small subunits. Each of these is a combination of protein and a type of RNA known as rRNA. At the beginning of translation, the two subunits form a structure around the mRNA molecule as the first tRNA (the one matching the first methionine or fMet) arrives. The completed ribosome has niches that hold up to three tRNAs at a time. Because a cell has so many ribosomes at any one time, rRNA is the most common type of RNA found in cells.
