Small RNAs generated at DNA break sites are implicated in mammalian DNA repair. Now, a study shows that following the formation of DNA double-strand breaks, bidirectional transcription events adjacent to the break generate small RNAs that trigger the DNA damage response by local RNA:RNA interactions.

RNA接管DNA断裂修复的控制。

在DNA断裂位点产生的小RNA与哺乳动物DNA修复有关。现在，一项研究表明，在形成DNA双链断裂后，与断裂相邻的双向转录事件会产生小的RNA，这些RNA会通过局部RNA：RNA相互作用触发DNA损伤反应。
