Web14 sep. 2024 · These multi-component molecular machines build complex proteins by stitching building blocks together according to instructions encoded in the cell’s messenger RNAs. But ribosomes are themselves composed of small and large subunits, each of which is made up of ribosomal proteins and RNA. Webribosomes During translation, as the ribosome moves down the mRNA strand, tRNAs will bring amino acids in at the A site. Translation is terminated when the A site on the ribosome reaches a (n) stop codon. a stop codon is encountered; ribosomal subunits dissociate a stop codon is encountered; ribosomal subunits dissociate termination
