DNA (deoxyribonucleic acid) is a nucleic acid that contains the genetic code for life. It also governs what traits you get and what you don't. DNA is made out of a series of four nitrogen bases: Thymine, Guanine, Cytosine, and Adenine. These nitrogen bases only pair with specific other bases, Adenine always pairs with Thymine while Guanine always pairs with Cytosine. the sides of a DNA ladder are made out of a sugar called deoxyribose and which lternated with another molecule known as phosphates.
