(an'tē-ter-min-ā'shŭn),

A process of bacterial RNA polymerase wherein it is resistant to pause, arrest, or termination signals. It is an important control mechanism in the reproduction of some bacteriophages.

antitermination

a process in which RNA POLYMERASE does not recognize a normal TRANSCRIPTION termination signal at the end of a GENE or OPERON during transcription and so transcribes the DNA beyond the terminator. Antitermination provides a means of regulating the EXPRESSION of genes.

In Southern California Indian Country two distinct interpretations of termination arose, as did two political grassroots organizations: pro- and antitermination.

Antitermination tribes managed to keep their lands under federal trust protection.

There was no middle ground for opinions regarding termination: you were either pro- or antitermination, and this resulted in fractures in family groups and factionalism between tribal relations.
