Chen Yongqun [Ruian City, Zhejiang Province seventh middle school (325211)] tRNA how to identify amino acids? Which What is the identification mechanism? Yang Guofeng [Gansu Province, Experimental County High School (742200] ribosomal 3 tRNA binding sites (A, P, E sites), each moving a codon distance. PEP 6, PEP 2, P.66, describes as: “Two tRNA binding sites are formed at the binding site between ribosome and mRNA.” Teaching materials in this sentence how
