Nucleotide excision repair is a major DNA repair mechanism in all cellular organisms. In this repair system, the DNA damage is removed by concerted dual incisions bracketing the damage and at a precise distance from the damage. Here, we review the basic mechanisms of excision repair in and humans and the recent genome-wide mapping of DNA damage and repair in these organisms at single-nucleotide resolution.
核苷酸切除修复是所有细胞生物中的一种主要DNA修复机制。在这个修复系统中,DNA损伤通过在损伤两侧进行协调一致的双切口切除,且切口与损伤保持精确距离。在此,我们综述了细菌和人类中切除修复的基本机制,以及近期在这些生物中以单核苷酸分辨率对DNA损伤和修复进行的全基因组图谱绘制。
