Ribosomal synthesis
Webb14 juli 2024 · Synthesis of Ribosome All of the cellular machinery necessary for ribosome synthesis is located in the nucleolus, a dense region of the nucleus that is not surrounded by membrane structures. The nucleolus is a variable structure depending on the cell type: it is large and conspicuous in cells with high protein requirements and it is an almost … WebbRibosome-inacttvatmg protein; Saporm 5; f/icra satin: Protein syntheses 1.
