CRISPR-Cas9 genome editing exploits the CRISPR-Cas system to modify a genome in a targeted manner. Guided by RNA, the Cas9 endonuclease breaks DNA at a target sequence. Imprecise repair of the double ...
Apurinic/apyrmidinic endonuclease 1 (APE1) plays a central role in DNA repair by cleaving the DNA backbone 5′ of AP sites that result from removal of damaged bases. New structural findings on APE1–DNA ...
