Alec Jeffreys Research Paper

Have you ever wondered how investigators figure out who the criminal is in the investigations? Is it luck or is it science? Forensic Science is the use of scientific principals to analyze information connected to a crime and who committed it. One type of forensics is autopsies. In the Rage and Bone Shop by Robert Cormier, investigators did some analysis of the crime scene, but should have used other forms of forensic science to solve the crime. The use of forensics in the novel hindered the investigation.

The popular television show, CSI: Crime Scene Investigations has been on the air for 12 years, and it has brought forth the behind-the-scenes actions of criminal investigations, even if its portrayals are not always scientifically accurate. This has caused an interest in the forensic sciences that has led most people to a skewed view of how a criminal investigation actually works. The reality of a criminal investigation is that it is generally more tedious and difficult than the theory of criminal investigation would have you believe. By examining the forensic and investigative procedures of the case of Pamela Foddrill, it is apparent that the theory of criminal investigation was not representative of the procedures concerning examination

Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect’s guilt or innocence (Butler, 2005). The method of constructing a distinctive “fingerprint” from an individual’s DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA

Forensic science can be defined as the relationship between law and science; it answers the questions of how, why and who committed the crime, with the input of multiple actors. However, there are currently problems with

After attending Sawyer Fredericks’ Hide Your Ghost tour, I can personally attest to his undeniable talent. Sawyer Fredericks provided an entertaining night that was enjoyed by all. Underground in the Valley Bar, Phoenix, the crowd swayed and sang along with his powerful, moving voice. With smiles on their faces and soul in their veins, fans left filled with contentment.

Due to the brief period that Hodge had been allowed to see her attacker, the prosecution felt that stronger evidence was needed to prove a connection. The brief 6-second glimpse that the victim Nancy Hodge obtained during her ordeal wasn’t considered viable enough for trial purposes (Lewis). This relatively new forensic investigation technic involving the use of DNA fingerprinting was in its infancy and was pioneered by a British scientist might hold the answer to convicting the rapist.

Life of Larry Levis Through His Poetry Larry Levis was an award-winning poet that lived a very short life, but with his contemporary writing style his legacy will always be remembered. Levis grew up on a grape farm in California, his family lived in poverty. Many of Levis’s writings were memories that he had as a child working on his family’s grape farm picking grapes and working with migrants. His poems take place from not only memories of his youth on the farm but also his experiences as a janitor at a steel mill and his time spent at the pool hall. With his exciting and surreal way of writing he ended up winning several awards.

Dr. Jeffrey Wigand, born in New York to strict parents, grew up in a Catholic household where he always had a passion for science. After graduating high school, Wigand attended community college before eventually joining the Air Force. After getting out of the service, he returned to college where he went on to earn his doctorate in biochemistry. Wigand worked in healthcare for companies such as Pfizer, Union Carbide, and Ortho Diagnostic System until he eventually landed a lucrative position with Brown & Williamson (B&W) in Louisville. He started out at the bottom, making a small salary until he accepted an attractive offer to become the research chief, head of research and development,

Forensic science is defined as the practice of utilizing scientific methodologies to clarify judicial inquiries. The field of forensic science contains a broad range of disciplines and has become a vital aspect of criminal investigations. Some forensic disciplines are laboratory-based; while others are based on an analyst’s interpretation of observable patterns (Kourtsounis, 2009). According to the Innocence project’s website; in greater than fifty percent of wrongful convictions, the use of invalidated or improper forensic techniques played a role in cases; which were later

After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime scene investigators will look at the photographs and connect their theories based on the crime that occurred. The forensic scientists will also examine the victim’s clothes, while the medical examiner will analyze the victim’s body for more clues and evidence that they may find and they will all be doing this in the crime lab. The things they may find could be hair, fiber, semen, blood, another person’s DNA, bruises and many more. After the forensic scientists

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;

Law Enforcement keep notes on arrests that have founded people innocent of crimes, and retention of an innocent person's DNA can be charge or otherwise, seen as a invasion of that person’s privacy and civil liberties. Dr. Alec Jeffrey, a former professor at the University of Leicester laboratory, consulted with his lawyers to develop the new type of technique called DNA profiling. His technique would prove that DNA fingerprinting (profiling) can individualize evidence compared to the blood typing. DNA profiling compares 13 standard STRs to form a profile. The analysis used by the scientists, uses PCR and STRs to profile an individual. It is highly unlike that two individuals’ identical numbers of repeats for all 13 STRs, will match, which DNA fails is hardly never due to a successful match of 385 million to 1. This makes DNA profiling the most accurate tool in Forensics.

Forensic science borrows from a number of sciences which include: physics, Biology and chemistry. It therefore involves examination of a wide spectrum as compared to any other method of investigation. Due to the wide spectrum of investigation and evidence analysis the method offers; it ensures that the results are accurate and can be used in the court of law to make a decision. The method establishes the existence of a crime, the connection between the crimes and the

DNA fingerprinting is a scientific technology involving the extraction, replication and arrangement of strands of an organism’s DNA. This results in the formation of a genetically distinctive fingerprint that is unique to the organism which the DNA sample was originally extracted from. Because of the specificity of a DNA fingerprint, the application of this technology can have a substantial influence on many aspects of society. Accessibility to a DNA database allows for higher efficiency in forensic investigations, personal identification, maternal and paternal testing. The availability of a national database to police officers and forensic scientists would equate to increased productivity in investigations and prosecution of suspects in a
