Answer 2

The correct answer would be TRUE. Both the internal and external environments can modify or alter a gene. Epigenetics is the study of the changes in organisms caused by the modification of gene expression. According to epigenetics, environmental conditions can indirectly affect our DNA. An example would be an exposure to a chemical agent or toxin, that may enter the cells of the tissue and interface directly with the genetic material. In addition, stress can also affect the modification of the genes.
