DNA on computer screen. Computer artwork representing computer-aided design (CAD) of the DNA (deoxyribonucleic acid) molecule. CAD of DNA molecules allows scientists to make slight changes to the DNA model on the computer screen. The computer will then calculate the overall effect of these changes on the molecule as a whole. This technique can be used in such fields as gene therapy, DNA drug-design, and genetic engineering.
