The elongation phase of transcription by RNA polymerase is highly regulated and modulated. Both general and operon-specific elongation factors determine the local rate and extent of transcription to coordinate the appearance of transcript with its use as a messenger or functional ribonucleoprotein or regulatory element, as well as to provide operon-specific gene regulation.

RNA聚合酶延伸因子。

RNA聚合酶转录的延伸阶段受到高度调控。一般和操纵子特异性延伸因子决定转录的局部速率和程度，以协调转录物的出现与其作为信使或功能性核糖核蛋白或调节元件的用途，以及提供操纵子特异性基因调节。
