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

Interrupted genes are longer than its mature RNA product because of the presence of the introns hence Length of precursor RNA (not mRNA) defines region of gene

Interrupted gene: Mutations in exons can affect polypeptide sequence; mutations in introns can affect RNA processing and hence may influence the sequence and/or production of a polypeptide.
