Human DNA can be sequenced from small amounts of water, sand, and air in the environment to potentially extract identifiable information like genetic lineage, gender, and health risks, according to our new research.
Every cell of the body contains DNA. Because each person has a unique genetic code, DNA can be used to identify individual people. Typically, medical practitioners and researchers obtain human DNA through direct sampling, such as blood tests, swabs, or biopsies. However, all living things, including animals, plants, and microbes, constantly shed DNA. The water, soil, and even the air contain microscopic particles of biological material from living organisms.
