DNA is short for Deoxyribonucleic acid. Every person has DNA inside of almost all of the cells in their body. It is the building block for each persons genetic makeup. No two people have the same DNA, and is inherited from parent to offspring (will be covered later). Most DNA is located in the the cell nucleus and some is located in the mitochondria. DNA is made up of four base pairs, A (Adenine), G (Guanine), T (Thymine) and C (Cytosine). In DNA Adenine always pairs with Thymine and Cytosine always pairs with Guanine. DNA has a specific structure and can be replicated ( will be discussed later). DNA is often compared to a blueprint that construction workers use before the actual construction of a building, because it contains the information needed for the entire body.
