How is an epigenetic change different from a mutation?
Epigenetics can be defined as the study of heritable changes that usually occur in gene expression as well as which do not involve the changes towards the underlying DNA sequence — The change in the phenotype without a change in genotype leads to affects how cells can read the genes. The process of occurrence of Epigenetic change is a regular and natural occurrence, but can also be stimulated by several factors including age, the environment/lifestyle.
A mutation can be described as the change in a DNA sequence. Mutations can result from the process of DNA copying mistakes made during cell division, and along with exposure to ionizing radiation and chemicals called mutagens, or infection proceeded by the viruses.
