Topoisomerase I prevents transcription-replication conflicts at transcription termination sites

Topoisomerase I prevents transcription-replication conflicts at transcription termination sites

R-loops have both positive and negative impacts on chromosome functions. To identify toxic R-loops, we mapped RNA:DNA hybrids, markers of replication fork stalling and DNA double-strand breaks along the human genome. This analysis indicates that transient replication fork pausing occurs at the trans...
