Detailed explanation-1: -Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence.
Detailed explanation-2: -Epigenetic tags record the cell’s experiences on the DNA, helping to stabilize gene expression. Each signal shuts down some genes and activates others as it nudges a cell toward its final fate. Different experiences cause the epigenetic profiles of each cell type to grow increasingly different over time.
Detailed explanation-3: -Interestingly, iPS experiments suggest that epigenetic features associated with aging can be reversed. In successfully reprogrammed iPSCs, the chromatin state of CDKN2A locus associated with aging is erased and restored to that of youthful cells (Meissner, 2010).
