Ribosomes Definitions:

  1. Ribosomes are complexes that make proteins. They float either freely in cytosol or are bound to rough ER or nuclear envelope.

  2. Ribosomes are the sites of translation. They are molecular complexes that facilitate the orderly linking of amino acids into polypeptide chains.

Ribosomes Notes:

Ribosomes comprise a complex macromolecular machine and are the primary sites where the protein translation takes place. Ribosomes are made up themselves by proteins and ribosomal RNA. They are scattered throughout the cytoplasm or are sometimes attaches to the surface of an ER. Ribosomes found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. Ribosomes consist of two major components: the small ribosomal subunits, which read the RNA, and the large subunits, which join amino acids to form a polypeptide chain.

Ribosomes Notes:

Ribosomes are important organelles found in almost all living cells. The ribosome is a complex molecular machine that serves as the site of biological protein synthesis. Ribosomes link amino acids together in the order specified by messenger RNA molecules and these amino acids are provided by the tRNA molecules.
