Fig. 2. Epigenomic hard drive (EHD) during chromatin alterations. (A) Diagram describes that a methyl and a phosphate group approach, causing addition of these groups respectively to chromatin. As this change is reversible methyl and phosphate groups get detached from chromatin. (B) This model depicts that SATB1 molecules bind to DNA sequence and cause chromatin remodelling with loop like formation of DNA, analogous to noodles, like shape of DNA for ease of transcription.
