A mRNA may be associated with several ribosomes (polysomes) in a cell actively engaged in protein synthesis. The process takes place in 4 major steps namely activation of amino acids, chain initiation, elongation and termination. Each step is controlled by specific enzymes and cofactors. Step # 1. Activation of Amino Acids: The amino acids are activated by a class of [...]
