Electrophoresis
magine a rape/ murder has just happened. The police go in to recover evidence. The only thing that can be found is a sample of DNA from a trace of blood on the victim. This DNA sample must be some how linked top the suspect. These DNA samples can be separated using gel electrophoresis. The number and position of bands formed on each lane of gel is the actual genetic "fingerprint" of that DNA sample. The characteristics of certain segments of DNA vary from person to person and form a highly individual, detectable "genetic fingerprint." This fingerprint is the most unique thing a person has, and therefore not two people have the same DNA sample. When the DNA sample form the crime scene and the DNA sample from the suspect are matched, then one can be sure that this is the right match. The suspect is guilty of the crime. Genetic fingerprinting by electrophoresis was only developed in the mid-1980s, genetic and has become a widely used courtroom tool. In 1988 the first person in the United States was executed based on DNA technology. Electrophoresis is a method that separates macromolecules whether it is nucleic acids or proteins, on the basis of size, electric charge, and other physical properties. The term electrophoresis
Physical mapping of the human genome. Analyzing the genomes of other species. An individual's DNA is as distinctive as a fingerprint. In 1988 the first person in the United States was executed based on DNA technology. Using this technology it is possible to separate and identify protein molecules that differ by as little as a single amino acid. We are now using biotechnology to study the basic processes of life, diagnose illnesses, and develop new treatments for diseases. Gel electrophoresis makes it possible to determine the genetic difference and the evolutionary relationship among species of plants and animals. For thousands of years people have used biotechnology by using yeast to make flour into bread and grapes into wine. The new techniques opened up the study of the molecular details of eukaryotic gene structure and function. Gel electrophoresis is a technique used for the separation of nucleic acids and proteins. The electrical current from one electrode repels the molecules while the other electrode simultaneously attracts the molecules. Today, hundreds of useful products are produced by genetic engineering, the manipulation of genetic material for practical purposes. This technique was used to assist in determining O. Biotechnology based on the manipulation of DNA in vitro (outside of living cells) is distinct from earlier phases in that it is more precise.
