Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. There are two groups of bases: Pyrimidines: Cytosine and Thymine each have a single six-member ring. Purines: Guanine and Adenine each have a double ring made up of a five-atom ring attached by one side to a six-atom ring. The order of nucleotides along DNA polymers encode the genetic information carried by DNA.
Your whole genetic code, the blueprint for your body and everything in it, is made up of is made up of a language with only four letters. DNA, the polymer that makes up the genetic code, is a sequence of nitrogen bases hung on a backbone of sugar and phosphate molecules and twisted into a double helix. The chain of nitrogen bases is translated into the proteins and enzymes that make up all of life in a system that has been described as elegant in its simplicity. The Four Nitrogen Bases, Plus One The four nitrogen bases that make up DNA are adenine, guanine, cytosine and thymine.
