Dual hairpin formation (Region 3-4 forms hairpin then second hairpin is formed between Region 1-2) release RNA-DNA hybrid and RNA Polymerase causes seizing transcription of trp operon at high trp concentration.

Attenuator riboswitch (Leader sequence) region 1 is translated atleast till codon 10 and 11 in case of Low trp concentration because ribosomes get stalled due to low availability of charged tRNA-trp

In case of Low trp concentration, RNA polymerase continues to EDCBA genes where new ribosome get attached to AUG of polycistronic genes

on attenuation for their control. In the case of the leucine operon, its leader peptide has four adjacent leucine codons, and the histidine operon leader peptide has seven histidine codons in a row.
