Discoveries in DNA, cell biology, evolution, and biotechnology have been among the major achievements in biology over the past 200 years with accelerated discoveries and insight’s over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be the most important and describe their significance to society, heath, and the culture of modern life.
DNA (deoxyribonucleic acid) is a self-replicating molecule or material present in nearly all living organisms as the main constituent in chromosomes. It encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Simply put, DNA contains the

In fact, drugs can even be custom made for a persons personal biochemistry and genetic make up. Diseases that were considered lethal and or that forms of treatment were non-existent, the discovery of DNA has led to break through drugs and treatments for those patients. DNA has also had significant impact in other areas outside of medicine. One such use is for establishing paternity which has an enormous impact on families and children. A person possesses two DNA copies. One is from the mother and the second from the father. The DNA from the mother and father (alleged father) are analyzed to evaluate paternity. DNA typing has a broad range of use besides parentage cases. Some of the more known or popular could be used to aid in criminal investigations, identification of mass disaster victims, and genetic ancestry of individuals. DNA can also be used in verifying the identity of human cancel cell lines and whether a biological material is of human origin (DNA Typing, 2007).
Another achievement in biology, biotechnology, which is the exploitation of biological processes for industrial and other processes, esp. the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.. “Biotechnology harnesses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet” (What is Biotechnology, n.d.).
