Attenuator riboswitch (Leader sequence) contains two major check-points in region 1

1. UGG codons on position 10, 11

2. A stop codon UGA between Region 1 and 2

#Unit 2. Cellular Organization

Attenuator riboswitch (Leader sequence) region 1 is translated  till UGA (R1-2) at high trp concentration due to two conditions

1. Ribosome quickly crosses codon 10, 11

2. After crossing codon 10, 11 ribosome prematurely terminated at UGA at the end of Region 1
