#Unit 2. Cellular Organization

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.

#Unit 2. Cellular Organization

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

#Unit 2. Cellular Organization

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

RNA Polymerase don’t get dissociated with one hairpin which is 2:3

Transcription is initiated at the beginning of the 162 nucleotide mRNA leader encoded by a DNA region called trpL.
