DNA end resection: mechanism and control

P Cejka, LS Symington - Annual review of genetics, 2021 - annualreviews.org
DNA double-strand breaks (DSBs) are cytotoxic lesions that threaten genome integrity and
cell viability. Typically, cells repair DSBs by either nonhomologous end joining (NHEJ) or …

DNA end resection during homologous recombination

R Gnügge, LS Symington - Current opinion in genetics & development, 2021 - Elsevier
Exposure to environmental mutagens but also cell-endogenous processes can create DNA
