how does dna work

DNA stands for deoxyribonucleic acid and is like a recipe book that tells our cells how to work. It is like a very long code made up of four different letters - A, C, G, and T. In your body, the letters in your DNA code can tell your cells what color hair and eyes you have, as well as what kind of disease you may get. Your cells read the letters in your DNA to figure out how to make all the different parts of your body.
