The mechanisms cells use to maintain genetic fidelity via DNA repair and the accuracy of these processes have garnered interest from scientists engaged in basic research to clinicians seeking improved treatment for cancer patients. Despite the continued advances, many details of DNA repair are still incompletely understood. In addition, the inherent complexity of DNA repair processes, even at the most fundamental level, makes it a challenging topic. This primer is meant to assist both educators and students in using a recent paper, "Promotion of homologous recombination by SWS-1 in complex with RAD-51 paralogs in Caenorhabditis elegans," to understand mechanisms of DNA repair. The goals of this primer are to highlight and clarify several key techniques utilized, with special emphasis on the clustered, regularly interspaced, short palindromic repeats technique and the ways in which it has revolutionized genetics research, as well as to provide questions for deeper in-class discussion.
细胞通过DNA修复来维持遗传保真度的机制以及这些过程的准确性,已引起了从基础研究科学家到寻求改善癌症患者治疗方法的临床医生的关注。尽管不断取得进展,但DNA修复的许多细节仍未完全了解。此外,即使在最基本的层面上,DNA修复过程固有的复杂性也使其成为一个具有挑战性的主题。本入门指南旨在帮助教育工作者和学生利用最近的一篇论文《秀丽隐杆线虫中与RAD-51旁系同源物复合的SWS-1促进同源重组》来理解DNA修复机制。本入门指南的目标是突出并阐明所使用的几种关键技术,特别强调成簇规律间隔短回文重复序列技术及其彻底改变遗传学研究的方式,并提供一些问题以供课堂深入讨论。
