DNA sequencing machine and insect example

This computerized picture represents a very small piece of the human genome or set of chromosomes with the genes they contain. Each color represents one of the four bases of DNA: adenine (green), cytosine (blue), thymine (red), and guanine (yellow), commonly abbreviated as A, C, T, and G.
