Abstract excerpt
Cells can repair DNA double-strand breaks by both homologous and nonhomologous mechanisms. To explore the basis of pathway utilization, we developed both plasmid and chromosomal yeast repair assays in which breaks are created with restriction endonucleases so that nonhomologous end-joining (NHEJ) competes with the single-strand annealing (SSA) recombination pathway, which we show acts with high efficiency via...
