SMART (Single Molecule Analysis of Resection Tracks) Technique for Assessing DNA end-Resection in Response to DNA Damage SMART(切除轨迹单分子分析)技术用于评估DNA末端切除对DNA损伤的反应 作者:Angela Altieri, Milena Dell’Aquila, Francesca Pentimalli, Antonio Giordano and Alfano Luigi日期:08/05/2020,浏览量:1017,Q&A: 0
DNA double strand breaks (DSBs) are among the most toxic lesions affecting genome integrity. DSBs are mainly repaired through non-homologous end joining (NHEJ) and homologous recombination (HR). A crucial step of the HR process is the generation, through DNA end-resection, of a long 3′ single-strand DNA stretch, necessary to prime DNA synthesis ...
