Deoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

Silverberg noted that the lifestyle factors linked to eczema and other health conditions -- such as smoking, drinking and obesity -- can be changed. Patients and doctors can work together to eliminate these bad behaviors and reduce the risk for heart disease and stroke, Silverberg said.
