WebExpert Answer. Tryptophan Operon Homework Unanswered Formation of the terminator loop during Trp attenuation is essentially a result of what action? o A In the presence of high trp, the 3-4 terminator loop forms as a result of the ribosome pausing at the two trp codons in region 1. ов In the presence of low trp, the 1-2 terminator loop forms ... WebSep 3, 2024 · A second mechanism, called attenuation, is also used to control expression of the trp operon. The 5′ end of the polycistronic mRNA transcribed from the trp operon has a leader sequence upstream of the coding region of the trpE structural gene. This leader sequence encodes a 14 amino acid leader peptide containing two tryptophan residues.
