Webii. In contrast to antibiotics that bind to the P site, those that block tRNA binding and bind to the A site of the bacterial ribosome would therefore affect the translation process in a different way. These antibiotics would prevent the addition of new amino acids to the expanding peptide chain by preventing aa-tRNA from binding to the A site. WebThe correct tRNA with its attached amino acid is selected at each step because each specific tRNA molecule contains a three-base sequence that can base-pair with its complementary code word in the mRNA. 3. …
