Researchers also continue to use DNA sequencing technology to learn more about everything from combating infectious disease outbreaks to improving nutritional security. Also known as DNA or genetic typing, DNA profiling is simply the collection, processing and analysis of VNTRs -- unique sequences on the loci (area on a chromosome). Wo James Watson (1928-), an American molecular biologist, received the Nobel Prize in Physiology or Medicine in 1962 with Francis Crick for their discovery of the structure of DNA. DNA typing is a laboratory procedure that detects normal variations in a sample of DNA (deoxyribonucleic acid). Mitochondria, often thought of as powerhouses of the cell, are fascinating eukaryotic organelles with a double-layered membrane and their own genome. At that time, he named it as " nuclein", which was later changed to " nucleic acids" and eventually to " deoxyribonucleic acid". The human hereditary material known as deoxyribonucleic acid, or DNA, is a long molecule containing the information organisms need to both develop and reproduce.

DNA holds the information the body uses to build cells. DNA forensics was first reported in 1984 by Dr. Alec Jefferys at the University of Leicester when he realized that DNA contained sequences that continued to repeat next to each other. During this process, DNA unwinds itself so it can be replicated. By developing a technique to examine the length variation of these DNA repeat sequences, Dr. Jeffreys created the ability to perform human identity tests. The discovery of DNA would eventually have a significant impact on science for years to come and still, today, remains a key area of research in the twenty-first century.
