EPIGENOME MARKERS JOURNALS

Epigenetics also refers to the changes themselves: functionally relevant changes to the genome that don't involve a change within the nucleotide sequence. samples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. organic phenomenon are often controlled through the action of repressor proteins that attach to silencer regions of the DNA. These epigenetic changes may last through cell divisions for the duration of the cell's life, and should also last for multiple generations, albeit they are doing not involve changes within the underlying DNA sequence of the organism; instead, non-genetic factors cause the organism's genes to behave express themselves. An epigenetic change in eukaryotic biology is that the process of cellular differentiation. During morphogenesis, totipotent stem cells become the varied pluripotent cell lines of the embryo, which successively become fully differentiated cells. In other words, as one embryo cell – the zygote – continues to divide, the resulting daughter cells become all the various cell types in an organism, including neurons, muscle cells, epithelium, endothelium of blood vessels, etc.
