Document Summary
Ribsome is a complex of rrnas and proteins that directs elongation of a protein. Subunits of ribosome are designated in svedberg units (s) S is a measure of sedimentation rate (velocity) of suspended particles when centrifuged under constant conditions. Velocity depends on both size and shape of the particle. It is a good measure of relative size if one is comparing same types of molecules. The assembled ribosome has three trna binding sites: They are placed in the cleft of the small subunit. They contain adjacent codons that are being translated into aa. Mechanism of protein synthesis can be divided into three stages: Initiation: the assembly of a complete ribsome on a mrna molecule at a correct point. Termination: the release of the new protein chain. If & ef: prokaryotic initiation and elongation factors eif&eef: eukaryotic initiation and elongation factors. Protein synthesis begins with initiator trna correctly positioned at start codon (aug=methionine)
