Epigenome

The Epigenome is a combination of many chemicals/proteins that are used to suppress or express (control) certain genes in a genome [1]. They maintain control of the genome by the use of methylation and the particular properties of histones [1]. Unlike the Genomic of organisms, epigenomic modification isn’t permanent allowing more adaptivity and flexibility to new environmental and lifestyle [2]. Epigenomic modifications don't physically change the genetics of the organism but like genomics, can be passed down for many generations[1]. Alteration of the epigenome is mainly seen in specialised cells to make them efficient in their function (this is done so by the process of deactivating/reactivating gene sequences in the genome) [1].
