What statement is NOT true regarding transcription attenuation of amino acid biosynthetic operons? 1.The leader peptide will contain multiple instances of the amino acid produced by the operon. 2.Transcription attenuation will always be accompanied by other positive or negative regulatory mechanisms. 3.Trancription will be reduced under conditions where concentration of the amino acid produced by the operon is high. 4.Synthesis of the leader peptide depends on the concentration of the aminoacylated tRNA, not the amino acid directly. 5.All of these statements are true.
