A) Example genomic region of MSL2 MNase-ChIP-seq profiles in early (stage 5-8, orange) and late (stage 13-15, purple) mixed-sex embryos. DNA binding is defined as sub-nucleosomal fragments (10 - 130 bp), while chromatin binding as mono-nucleosomal fragments (130 - 220 bp). Called peaks/regions are represented as boxes above the tracks and HAS below. Late-appearing regions are marked by a plus (+) sign. Graph represents pooled IP/Input signal of 3 biological replicates.
