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. Gene expression refers to how often or when proteins are created from the instructions within your genes.
Detailed explanation-2: -Several lifestyle factors have been identified that might modify epigenetic patterns, such as diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress, and working on night shifts.
Detailed explanation-3: -Environmental influences, such as a person’s diet and exposure to pollutants, can impact the epigenome. Epigenetic modifications can be maintained from cell to cell as cells divide and, in some cases, can be inherited through the generations.
Detailed explanation-4: -Epigenetic mechanisms form a layer of control within a cell that regulates gene expression and silencing. Three different epigenetic mechanisms have been identified: DNA methylation, histone modification, and non-coding RNA (ncRNA)-associated gene silencing. More items •08-Aug-2022
