Though each individual's DNA fingerprint is unique, most forensic tests do not analyze the entire genome but focus on tiny regions known to be highly variable from one person to another.
Some states now save DNA data from convicted criminals.
Environmental Uses of DNA Technology Scientists are engineering metabolic capabilities of organisms so they can transform chemicals and thus help solve environmental problems. As metal reserves are depleted, genetically engineered microbes may perhaps be used in mining and in cleaning up mining waste. Metabolic diversity of microbes is used in the recycling of wastes and detoxification of toxic chemicals Sewage treatment plants use microorganisms to degrade organic compounds into non-toxic forms. Biologically and chemically active compounds that cannot be easily degraded are often released into the environment. The intent is to engineer microorganisms that can degrade these compounds and can be used in waste water treatment plants.
