An Overview of DNA

DNA, or deoxyribonucleic acid, is a nucleic acid that houses the genetic code that is used in the functioning and development of all living things. The purpose of DNA is the permanent storage of genetic information, which is similar to a blueprint design that engineers would use to build a structure. Each organism has its own unique DNA make up. This is how crime scene investigators are able to make positive identifications of criminals when just a sample of blood, saliva, or hair is left behind. The uses of DNA range from forensics to genetic engineering and can be used in the fields of anthropology and history. DNA can be studied in a variety of ways, including the properties, chemical modification, biological functions, interactions with proteins, and its use in technology.
