Scientist testing DNA samples. DNA (deoxyribonucleic acid) is the genetic material that controls the growth and development of living organisms. DNA testing involves amplifying the DNA in a sample and identifying the genetic sequence. This information can be used in medicine to test for inherited (genetic) diseases. It can also be used to determine parentage. Samples from a crime scene can be tested to identify potential suspects in a technique known as DNA fingerprinting or DNA profiling. Filmed in 1990 | |
