Ribosome composed of

Each ribosome is composed of small (30 S) and large (50 S) components, called subunits, which are bound to each other: (30S) has mainly a decoding function and is also bound to the mRNA (50S) has mainly a catalytic function and is also bound to the aminoacylated tRNAs. Visa mer Ribosomes are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons Visa mer Ribosomes were first observed in the mid-1950s by Romanian-American cell biologist George Emil Palade, using an electron microscope, as dense particles or granules.
