Its RNA polymerase activity was dependent upon the primer in vitro with limited reverse transcription activity.

其RNA依赖的RNA聚合酶活性有一定的引物依赖性。

Actin was also reported to co-purify with RNA polymerase II and to be required for efficient in vitro transcription by RNA polymerase II.

肌动蛋白还能与RNA聚合酶II共纯化，对RNA聚合酶II体外的有效转录起到作用。
