Why It Matters: DNA Structure and Replication

Why relate DNA structure to the process of DNA replication?

DNA is responsible for all the physical traits that make you function as a human organism. It plays a vital role in life on this planet. DNA stores genetic information. In a sense, it is a type of biological hard drive. Your DNA is unique to you. Personalized medicine is a growing area of medicine that utilizes your genetic uniqueness. Understanding DNA can help a doctor prescribe medicine and treatments that are tailored to your individual needs, based on how your body will metabolize drugs or respond to treatment options.
