The full name of DNA is deoxyribonucleic acid, which is an important part of chromosome. People, animals and plants all have DNA. Each individual's DNA is different. It is human's genetic material and contains all the genetic characteristics. That is to say, a person's physical characteristics, organ functions and even personality are determined by DNA.

DNA defects will appear in many patients with congenital diseases. If DNA mutation occurs, it may also lead to tumor. DNA detection in clinic is helpful for the diagnosis of gene defect diseases. The monitoring of DNA, such as bacteria and viruses, can help to determine whether there are infectious diseases.
