Tchurikov et al. (2015a, 2016) Tchurikov et al. (2015a, 2016) [7,9] have made major advances in this direction, reporting that sites of human genome double-strand breaks (DSBs) occur frequently at sites in rDNA that are tightly linked with active transcription - the authors used a RAFT (rapid amplification of forum termini) protocol that selects for blunt-ended sites.
