The initiation of RNA transcription by the virion-bound RNA transcriptase of vesicular stomatitis virus has been examined. Multiple initiation sequences have been observed, two of which have been characterized (pppApCpGp... and pppGpCp...) suggestive of a transcription process which can start at different sites along the template RNA. By the use of sequential labeling techniques and exonucleases, it has been determined that there is a 5' to 3' direction of product RNA synthesis.
对水泡性口炎病毒的病毒体结合RNA转录酶启动RNA转录的过程进行了研究。观察到多个起始序列,其中两个已被鉴定(pppApCpGp...和pppGpCp...),这表明转录过程可以沿着模板RNA在不同位点起始。通过使用连续标记技术和核酸外切酶,已确定产物RNA的合成方向是5'到3'。
