Protein biosynthesis, in other words, translation, is the overall process of gene expression. It occurs in the cytoplasm near the ribosomes. In translation, RNA is decoded and to produce and certain polypeptide according to the generic code. This sequence is a template to guide the synthesis of amino acids to form a protein. Transfer RNA, (tRNA) is a mall RNA that transfers certain amino acids to the growing polypeptide chain near the site of protein synthesis in the ribosomes. This process is responsible for providing the protein in most cells. There are 4 steps to translation: activation, initiation elongation, and termination.

There is also two types of translation. Prokaryotic and eukaryotic. Prokaryotic translation is the process by which messenger RNA is translated into proteins in prokaryotes. Eukaryotic translation is the process by which messenger RNA is translated into proteins in eukaryotes. It consists of initiation, elongation and termination.
