WebDNA replication massively disorders chromatin composition and structure, and how accessible regions are affected by and recover from this disruption has been unclear. Here, we present repli-ATAC-seq, a protocol to profile accessible chromatin genome-wide on replicated DNA starting from 100,000 cells. WebIn most mammals, including humans and mice, the size of the chromosome is ~16,000 base pairs and unlike nuclear DNA, mitochondrial DNA (mtDNA) is not densely compacted. This results in mtDNA to be highly accessible for enzymes such as the Tn5 transposase, commonly used for accessible chromatin profiling of nuclear chromatinized DNA.
