Webb31 dec. 2024 · The initiation phase of protein synthesis involves the formation of a complex between the ribosomal subunits, an mRNA template and tRNAfmet (Fig. 8.5). A 30S subunit attaches to the ribosome-binding site as described above. tRNAfmet then interacts with the AUG initiation codon, and finally the 50S ribosomal subunit attaches. WebbA ribosome is a complex macromolecule composed of structural and catalytic rRNAs, and many distinct polypeptides. In eukaryotes, the nucleolus is completely specialized for the synthesis and assembly of rRNAs. Ribosomes exist in the cytoplasm of prokaryotes and in the cytoplasm and rough endoplasmic reticulum of eukaryotes.
