These tracks show the micrococcal nuclease (MNase) accessibility (MACC) of the D. melanogaster genome. Chromatin from D. melanogaster were digested using four different concentrations of MNase (1.5, 6.25, 25, and 100U). The digested DNA fragments are either sequenced as whole-chromatin extract (c-MACC), or after chromatin immunoprecipitation of histones H3 and H4 (h-MACC). The pooled evidence tracks were constructed by averaging the signals from the four concentrations of MNase.
The datasets were retrieved from the Gene Expression Omnibus database at NCBI under the
accession number GSE78984.
The results were lifted from the D. melanogaster release 5 assembly to the release 6 assembly.
