在真核生命中，遗传信息载体DNA分子被一类特殊的蛋白-组蛋白（histone）有序地组织起来，逐级形成核小体（nucleosome）、染色质纤维（chromatin fiber）、染色质环（chromatin loop）、染色质TAD等关键中间结构，最终组装成具有复杂拓扑结构的染色质，将DNA层层包裹。所有与DNA有关的生命活动（比如DNA复制、修复、重组、基因转录等）都需要将这层层被包裹的DNA...

单分子力谱指纹揭示转录辅助因子FACT的双面性
单分子力谱指纹 转录辅助因子FACT

两句耳熟能详的俗语“龙生龙，凤生凤”和“龙生九子各不相同”道出了生物遗传现象中两个关键的特点：相似性和特异性。人类基因组精确测序显示人类基因的差异很小（<0.3%），这解释了遗传相似性的来源；另一方面，基因被一类称为组蛋白的生物大分子通过层层组装形成高度有序的染色质结构，受重塑因子、组装因子、组蛋白和DNA的化学修饰以及组蛋白变体等多种因素影响，导致了遗传的特异性。单分子操纵技术是研究染色质动态调...
