Dna rna hybrids play a physiological role in cellular processes, but often, they represent non scheduled co transcriptional structures with a negative impact on transcription, replication and dna repair. accumulating evidence suggests that they constitute a source of replication stress, dna breaks and genome instability. reciprocally, dna breaks facilitate dna rna hybrid formation by releasing. Chromatin domains and their associated structures must be faithfully inherited through cellular division to maintain cellular identity. however, accessing the localized strategies preserving chromatin domain inheritance, specifically the transfer of parental, pre existing nucleosomes with their asso ….

Nucleosome assembly during dna replication is tightly coupled to ongoing dna synthesis. this process, termed dna replication coupled (rc) nucleosome assembly, is essential for chromatin replication and has a great impact on both genome stability maintenance and epigenetic inheritance. this review discusses a set of recent findings regarding the.
