What Does Attenuation Mean in Microbiology

The response of the synthesis of bacterial mRNA to the nutritional state of the organism, e.g. the decrease in transcription of the trp operon in the presence of tryptophan, which is due to the incomplete transcription of a leader mRNA sequence coded for by the attenuator sequence.

What is attenuation in microbiology?

In genetics, attenuation is a proposed mechanism of control in some bacterial operons which results in premature termination of transcription and is based on the fact that, in bacteria, transcription and translation proceed simultaneously.

What are attenuators in transcription?

Transcriptional attenuation is a regulatory mechanism that causes premature termination of transcription under certain conditions, thereby preventing the expression of the mRNA required for expression of the corresponding gene products.
