5) Translation was originally sorted out using a variety of inhibitors of protein synthesis Inhibitors tend to interrupt the process at a particular step and a population of translating ribosomes will all stop in the same state. An allied technique is to identify temperature sensitive mutations in various accessory factors. When the population of ribosomes is shifted to the restrictive temperature, ribosomes will stall when they need the function of the mutant protein to continue By analyzing the structure of...
