The epigenome contains the majority of the chemical compounds that have been added to entirety of one’s DNA (genome) as an approach to control the expression of all the genes inside the genome. The substance mixes of the epigenome are not part of the DNA sequence, but rather are attached to DNA. Epigenomic changes stay as cells divide and sometimes again can be acquired in next generation. Natural impacts, for example, a persons diet and exposure to pollutants, can likewise affect the epigenome. Epigenetic changes can help decide if genes are turned on or off and can impact the generation of proteins in specific cells, ensuring that only necessary proteins are produced.
