WebA ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain). WebAfter the formation of the initiation complex, the 30S ribosomal subunit is joined by the 50S subunit to form the translation complex.
