Genomewide nucleotide-resolution mapping of single-strand breaks and lesions by GLOE-Seq [Human_Ligase_inactivation]

ABSTRACT: Numerous methods are available for the mapping of DNA lesions ranging from double-strand breaks (DSBs) to incorporated ribonucleotides. We now present a technology based on the Genomewide Ligation of 3’-OH Ends (GLOE-Seq) and an associated computational pipeline designed for single-stranded breaks (SSBs), but versatile enough to be applied to any lesion that is convertible into a free 3’-OH terminus. We demonstrate its applicability to the mapping of Okazaki fragments without prior size selection and detect biases and asymmetries in the distribution of spontaneous SSBs in budding yeast and human DNA.
