The Integration of DNA Applications in Forensic Science

Elizabeth Gibbens The Integration of DNA Applications in Forensic Science Abstract Locard's Principle of Exchange states that when any person comes into contact with an object or another person, a cross-transfer of physical evidence occurs. The identification of that physical evidence has been the pivotal point in forensic work since Francis Galton developed a system of fingerprint classifications in 1892. Forensic science has rapidly evolved from using fingerprint identification to using a person's genetic makeup through a whirlwind of technology that has reshaped the Criminal Justice System. DNA analysis has become the most important tool for human identification and sorting unidentified remains by cataloging genetic markers. This paper will first examine how analyzing genetic markers first found in blood has evolved to analyzing DNA for direct mutations and how using amplification techniques have allowed the smallest biological samples to be identified. Second, this paper will review how the acceptance of these technological advances throughout many jurisdictions has necessitated the standardization of qualification and validation methods to leave no room for doubt of the reliability of data in a court of law. Third, the movement from retaining samples as evidence into creating a computerized data banking systems will be explored and the policies it has affected

Using DNA to Solve Crimes.

Forensic Science Using DNA to Solve Crimes The past decade has seen great advances in a powerful criminal justice tool: deoxyribonucleic acid, or DNA. DNA can be used to identify criminals with incredible accuracy when biological evidence exists. By the same token, DNA can be used to clear suspects and exonerate persons mistakenly accused or convicted of crimes. In all, DNA technology is increasingly vital to ensuring accuracy and fairness in the criminal justice system. News stories extolling the successful use of DNA to solve crimes abound. For example, in 1999, New York authorities linked a man through DNA evidence to at least 22 sexual assaults and robberies that had terrorized the city. In 2002, authorities in Philadelphia, Pennsylvania, and Fort Collins, Colorado, used DNA evidence to link and solve a series of crimes (rapes and a murder) perpetrated by the same individual. In the 2001 "Green River" killings, DNA evidence provided a major breakthrough in a series of crimes that had remained unsolved for years despite a large law enforcement task force and a $15 million investigation. DNA is generally used to solve crimes in one of two ways. In cases where a suspect is identified, a sample of that person's DNA can be compared to evidence from the crime scene. The results of this comparison may help establish whether the suspect committed the crime. In cases

The Ethics of Human Cloning.

The Ethics of Human Cloning For the purposes of this essay, "human cloning" will refer to human reproductive cloning involving somatic cell nuclear transfer (explained later), rather than therapeutic human cloning, which involves the use of pluripotent stem cells. Advances in cloning research have used (differentiated) somatic cells. Essentially any cell within body could be used to make a clone, be it a neuron or a hepatocyte or myocyte, it still contains all the genetic material and instruction to create a new identical organism. It was the birth of "Dolly" the sheep in 1997 that highlighted the possibility that the cloning of human beings is possible. The process of somatic cell nuclear transfer involves obtaining a donor oocyte and removing its genetic contents, to produce an "enucleated" cell. Cloning techniques involve obtaining a somatic cell from the person to be cloned and fusing it with the enucleated cell via electrofusion, which both fuses and activates the new cell. The somatic cell sample is primarily "starved" to prevent it copying any more of its DNA. Fusion of two cells in such a technique results in the mixing of the mitochondrial contents of both cells. Mitochondrial DNA is thought to have little effect on the cell and organism (providing there is no mitochondrial disease).The resulting embryo is then implanted in to the host female or surrogate

Public awareness of Cloning

Introduction Cloning could only happen in science fiction movies but now it seems like it is becoming a reality or is it? In this 21st century, anything is possible and this has been proven when the first man landed on the moon. Now there are talks of cloning going around and arousing suspicions in each persons mind. What is cloning? It is simply a term used when producing an identical of something but 'what' is the question. The discovery of DNA proved to be the ultimate discovery of all time as scientist has a better understanding of what we are. .1 Background Information Ever since the discovery of DNA or Deoxyribonucleic Acid, there had been amazing discoveries that had helped human race especially in the world of medicine and farmers in increasing the food production. Each year, scientists become more aware of what DNA is and how we inherit some characteristics from our parents. Then questions on possible cloning began to stir. Tests were carried out, experiments were done on animals and the results were both devastating and amazing. First of all, what is DNA cloning? To different people it has different meaning. According to a website www.cancerweb.ncl.ac.uk, DNA cloning is 'the use of DNA manipulation procedures to produce multiple copies of a single gene or segment of DNA'. 1970's was when animal cloning began and the animal that was usually tested on was mice.

Blood Factors and the DNA Fingerprint.

Blood Factors and the DNA Fingerprint Teri Davis Research Paper Summer 2003, Friday Mr. Speener While fingerprinting is still the only surefire way to separate identical twins, DNA testing provides its own advantages. I. Blood Typing A. A, B, O, and AB B. Rhesus Factor C. Deoxyribonucleic acid II. DNA Fingerprinting A. DNA typing 1. RFLP, PCR, STR III. Gathering Evidence at Crime Scenes A. Locations B. Storage IV. CODIS Conclusion: CODIS is used in the national, state, and local index system networks to link typing results from unsolved crimes with cases in multiple jurisdictions or persons convicted of offenses specified in the data banking laws passed by the jurisdictions. Blood's individual qualities were recognized years ago when doctors realized some transfusions were successful while others were immediately fatal. From observation came the ABO typing system and the first understanding of the Rhesus factor. While there are extremely rare or exotic blood types, most people can be classified into the A, B, O, or AB blood types. The fact that an AB type exists at all told early investigators that every individual actually carries two alleles, or traits that determine blood type-one inherited from each parent. Further studies proved that if each parent contributed an O allele, the child would be type O, but if one parent contributed an A and

Introduction So The Lord God caused the man to fall into a deep sleep; and while he was sleeping, He took one of the man's ribs and closed up the place with flesh. Then The Lord God made a woman from the rib He had taken out of the man, and He brought her to the man. The man said, "This is now bone of my bones and flesh of my flesh; she shall be called 'woman,' for she was taken out of man." For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh. (Genesis 2:21-24). I believe that over time God has given the human race many great skills in order to progress, skills such as: the power to fly,
