A DNA metabolic process that results in the disassembly of R-loops. R-loops are three-stranded nucleic acid structures consisitng of an RNA:DNA heteroduplex and a looped-out non-template strand. Aberrant formation and persistence of R-loops block transcription elongation and cause DNA damage. Mechanisms that resolve R-loops are essential for genome stability. [PMID:28790157]
