When histones are tightly intertwined with the DNA strand, the DNA is unable to be read. In addition, chemical changes performed on the surface of histones can then change the association of the protein in the segment of DNA (WIlliams). In the case of identical twins, the process of inactivation and activation could explain variance in the identical genetic sequence. According to a Spanish twin study, “the patterns of DNA methylation and modification in identical DNA strands exhibit ‘remarkable’ differences” based on identical twin’s DNA later in life compared to their indistinguishable strand early in life (Powledge). The differences in patterns of alteration in the identical DNA strand exhibits the effects the environment displays in the genome. The silencing or activation of a gene could in turn, determine the individual’s development of a disease, or phenotypic expression portrayed by the personal
