Polarity Of Transcription Definition in Medical Conditions Dictionary

Polarity of Transcription:

Decrease in the synthesis of proteins specified by genes distal to the operator and to the site of a nonsense, frameshift, deletion or insertion mutation in an operon. A mutation which produces polarity is called a polar mutation or a polarity mutation.
