A genome is a master blueprint over the course of an organism's lifetime. It is tiny, but it contains a vast amount of information. Scientists are working to understand the secrets of our DNA and that of the plants and animals used in agriculture. But the amount of information in a genome is so complex, they need help organizing and analyzing it. That's where computers come in.
Computers are the information-storers of our world.
When they're applied to the study of DNA, they give scientists a unique window into the submicroscopic world. They use a branch of biotechnology called genomics. Genomics allows scientists to find and sequence the genes of living organisms. Genome sequencing starts with genetic markers as reference points. Genetic markers were first identified when scientists learned how to take a genetic fingerprint of an organism.
