  Can the Environment change your DNA? What is DNA? Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries the genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are connected by chemical bonds between the bases: adenine bonds with thymine, and cytosine bonds with guanine. The sequence of the bases along DNA’s backbone encodes biological information, such as the instructions for making a protein or RNA molecule. Can DNA be changed by the environment? While the sequence of DNA may not be affected by your environment, the way genes work—called gene expression—can.   Think of DNA as a computer’s hardware; there may be several ty
