Since we are all about programming cells, we need code. The code we use isn't RNA or protein or small molecules, instead it's the specific sequence of a DNA molecule. We write code by putting pieces of DNA together, each of which has a particular function. To use a different metaphor, the parts we use to build systems are DNA molecules. That's why DNA molecules in the registry are referred to as parts rather than DNA. Finally note that the Registry doesn't have entries for mRNA or small molecules. We should, and we'll get to those as soon as we can. Go back to the start->
