DNA or deoxyribonucleic acid, are molecules that hold our genetic information. The most common term for DNA is “genes”. The structure of the molecule is a double stranded helix. There are two backbones that run in opposite directions. The “ladder” part of the DNA holds the genetic information.
Genetic information is coded using four nucleotides called guanine, adenine, thymine, and cytosine. The order of these nucleotides dictate how the protein building blocks make up your body structure. This genetic code tells your body how tall you will be, where to store body fat, what color your hair is, etc.
DNA can be found bundled up in any cell that has a nucleus. A nucleus is basically the cell manager. Most cells in the body have a nucleus that tells them what to do and when. The nucleus basically manages each individual cell according to the DNA that it contains.
