Ribosomes ( / ˈraɪbəzoʊm, - soʊm /) are macromolecular machines, found within all cells, that perform biological protein synthesis ( messenger RNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.
Jun 27, 2024 · Ribosomes are the sites at which information carried in the genetic code is converted into protein molecules. Ribosomal molecules of messenger RNA (mRNA) determine the order of transfer RNA (tRNA) molecules that are bound to nucleotide triplets (codons).

3 days ago · A ribosome is the cellular machinery responsible for making proteins. There are many ribosomes in each cell, each made up of two subunits. These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon.
Jun 1, 2023 · Biology definition: The ribosome is a cytoplasmic structure that is minute and sphere-shaped. It is composed of protein and ribonucleic acid (RNA). As the famous ribosomes analogy to factories suggests, they serve as the site of protein synthesis; protein factories.
A ribosome is a complex molecule that synthesizes proteins from amino acids using mRNA as a template. It consists of a large and a small subunit, each with ribosomal RNA and proteins, and is found in the cytoplasm of cells.
