Stages of protein synthesis. Illustration of the stages in protein synthesis in cells: initiation (top),elongation (middle),and termination (bottom). Messenger ribonucleic acid (mRNA,red) is read by ribosomes (blue),moving from the 5' to the 3' end of mRNA. The first transfer RNA (tRNA,key-shaped) and amino acid (orange dot) binds to the ribosome's P site (upper centre). Incoming tRNA fragments bring more amino acids to the A site,with the polypeptide chain growing (centre) from the P site until the termination codon is reached (bottom). A release factor (purple) frees the ribosome subunits until needed again. For this artwork with labels,see C023/8874 | |
