The sides of the DNA ladder are made up of a combination of alternating sugars and phosphates. These molecules are what holds the rungs of DNA together on the ladder.
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.
