genome.jpgHuman genomes can change throughout a person’s lifespan. It’s influenced by environmental or nutritional factors. This change may explain the reasons for different deadly illnesses such as cancer which comes with age. Researchers at Johns Hopkins University found epigenetic marks on a DNA sequence which modify over the course of one’s life. The extent of such changes is similar among family members. The changes in the genomic structure can occur as a result of dietary and other environmental exposure. Epigenetics may play a role in diseases like diabetes, autism and cancer.
