BIO206H5 Lecture Notes - Lecture 14: Aminoacyl-Trna, World Federation Of Trade Unions, Svedberg
Document Summary
Functional sites: a, p, e, ef-tu, ef-g, mrna trna & rrna transcript processing. Can see the small grains that are the ribosomes need lots of ribosomes as the cell continuously is making thousands of proteins. Sites of protein synthesis where ribosomes are found. Lot of biosynthesis is required to make necessary ribosomes. Remain free in cytosol if not in use . Ribosome subunits are dissociated from each other in the cytoplasm pool. Ribosomes attached to er are actually synthesizing protein. Note that the reaction is actually taking place in the cytoplasm in all cases (we will see later how transfer into the er takes place) The complex for protein synthesis is assembles and translation occurs either in cytosol or into er depending on properties of the mrna. Ribosomes subunits dissociate and are returned to the pool where they can start again in the cycle. Synthesis of proteins and rrna rrna and proteins assemble to subunits.
