Exons are usually short, typically encoding fewer than 100 amino acids

Exon sequences are conserved by the negative selection of individuals in which the sequences have changed.

The protein DskA  also plays an important role. It binds to RNA polymerase and reduces the lifetimes of the rrn open promoters to a level at which they are responsive to changes in iNTP and ppGpp concentrations.
