Epigenetic and its phenomenon

Gene expression, regulates cell properties. While some genes candidate for cell activity, the others repressed for long time. Eukaryote cell remind Gene expression pattern even in absence induction agent. Epigenetic refer a term encompassing every mechanism that results in heritable changes to gene expression without affecting the DNA sequence. Epigenetic mechanism consists of biological process from the zygosis till death, such as gametogenesis, Embryo formation, cell development and diffraction. The most major epigenetic control related to Chromatin rearrangement, Histone modification, DNA methylation, non-coding RNA activity.
