DNA, genes and genomes

DNA, Genes and Genomes


Carried within almost every one of our hundreds of trillions of cells is a complete set of instructions for making a human being. These instructions are in the form of a chemical code.

The structure of the code is deceptively simple, and yet it includes all of the instructions required to make a living thing: a human, or a cauliflower, or a tree frog, or whatever.
