ABSTRACT
Epigenetic studies the changes in gene function and gene expression that are not discernable by mutations in the DNA sequence. The area of biology devoted to epigenetic is a recent development and has a large amount of room for growth with new research on cancer, mammalian gene expression, and technological advances constantly being brought forth from the community. Epigenetic inheritance focuses on both mitotic and meiotic cellular changes and the processes involved. Looking at cell differentiation and genetic imprinting through epigenetic has created new leads for cancer research in terms of tumor growth. The chromatin that controls DNA processes is an epigenetic mechanism in either an active or repressive state. There are three main mechanisms in epigenetic: DNA methylation, histone modifications, and the binding of non-histone proteins [1].
