WebAbstract. R-loop is a type of three-stranded nucleic acid structure that is made up of an RNA:DNA hybrid, formed due to failing separation of a nascent RNA molecule with transcripting template in transcription or by the re-annealing of RNA molecule with one of the two strands in a double stranded DNA molecule, along with the single stranded DNA ...
