By convention, theamino acids within a polypeptide are numbered from the aminoterminalend to the carboxyl-terminal end. Are the following questionsabout lactose permease true or false?A. Because the sixty-fourth amino acid is glycine and the sixty- eighth amino acid is aspartic acid, the codon for glycine,64, is closer to the 3′ end of the mRNA than the codon for aspartic acid, 68.B. The mRNA that encodes lactose permease must be greater than1241 nucleotides in length.arrow_forward
