在这里，作者表明，利什曼原虫中不寻常的染色体大小依赖的DNA复制时间受到RNA-DNA杂交的影响，这种杂交被内切酶RNase H1识别。 探秘利什曼原虫基因组：R 环与 RNase H1 对 DNA 复制及基因组稳定性的影响 近日，来自格拉斯哥大学寄生虫学中心（The University of Glasgow ...

二、实验环境的特殊要求：高度洁净且防酶污染 RNA实验对实验环境的洁净度要求极高。空气中漂浮的微粒、细菌以及实验器材上的微小污染都可能成为RNase的来源，从而污染RNA样本。因此，RNA实验需要在专门的洁净实验室中进行，并定期对实验器材进行去RNase处理。

Bacterial mRNAs begin with a triphosphate on the first transcribed nucleotide, but RNase E, the endonuclease long thought to initiate mRNA decay in Escherichia coli, only works well on RNA with a ...

"天然马达蛋白在生物过程中发挥着至关重要的作用，其速度可达 10-1000 nm/s。到目前为止，人工分子马达还难以达到这样的速度，大多数传统设计的速度还不到 1 nm/s，"该研究的第一作者、研究员 Takanori Harashima 说。

“我们首次在接近生理浓度（毫摩尔级别）的镁离子环境下，直接观察到 RNA 分子的动态行为，完全颠覆了对 RNA 的传统认知。”美国国家癌症研究所王运星教授表示。他所提到的，是其团队近期在 Nature 同一期连续发表两篇“背靠背”论文中的研究结果 ...
