转录延伸 meaning in English
transcription elongation
Examples
- Deletion of elp3 ( or other elp genes ) confers a set of phenotypes , some of which are associated with elongation defects
缺失yelp3 (或其它yelp )可导致一系列表型，有的与转录延伸缺陷有关。 - Recent data have demonstrated that the tails of histones h3 and h4 greatly reduce the speed of transcript elongation through a nucelosome , and tail acetylation suppresses this effect
近来研究表明组蛋白尾部尤其是h3 、 h4四聚体的尾部强烈影响通过核小体的转录延伸速率，而尾部的乙酰化修饰可抑制这种影响。 - Recently , human elongator complexes have been isolated . the human complex is a fragile six - subunit complex that interacts with rnap ii and has hat activity directed against histone h3 and h4 . depletion of elongator from hela nuclear extracts reduces the ability of these extracts to transcribe chromatin templates , providing biochemical support for the proposed role of elongator during transcript elongation in chromatin
近来人elongator也被分离，它也是个不稳定的六亚基复合物，可与rnap相互作用，具有hat活性，能乙酰化h3和h4 ，在hela细胞核抽提物中去除elongator可降低抽提物对染色质模板的转录延伸速率，提供了该复合物在染色质为模板的转录延伸中有功能的生化证据，但是上面的信息都来自体外研究。
