We provide here a molecular movie that captures key aspects of RNA polymerase II initiation and elongation. To create the movie, we combined structural snapshots of the initiation-elongation transition and of elongation, including nucleotide addition, translocation, pausing, proofreading, backtracking, arrest, reactivation, and inhibition. The movie reveals open questions about the mechanism of transcription and provides a useful teaching tool.
我们在此提供一段分子电影,捕捉 RNA 聚合酶 II 起始和延伸的关键方面。为了创建这部电影,我们结合了起始延伸转变和延伸的结构快照,包括核苷酸的添加、移位、暂停、校对、回溯、停滞、重新激活和抑制。这部电影揭示了关于转录机制的悬而未决的问题,并提供了一个有用的教学工具。
