Attenuation in the control of expression of bacterial operons

摘要: Bacterial operons concerned with the biosynthesis of amino acids are often controlled by a process attenuation. The translation product initial segment transcript each operon is peptide rich in acid that particular controls. If short supply stalled at relevant codons long enough for succeeding to form secondary structures allow transcribing RNA polymerase molecule proceed through site otherwise dictates termination transcription. This attenuator;
