DNA has shaped all organisms and shows the genetic code that makes us who we are today. DNA stands for deoxyribonucleic acid a double helix structure. It is like a twisted ladder with unequaled attributes. It has the ability to store genetic information, copy it, and pass it from generations to others making a unique genetic code. DNA profiling, the analysis of DNA samples to establish if they come from the same person has been used in many situations over the past few decades for identification. This has revolutionized science tremendously. It had changed and improved how forensic science is performed. DNA profiling, especially in crime scenes has been a matter of life or death in many stories. Over the years the analysis of DNA evidence …show more content…

Anderson had an alibi. At the time that the murder was committed, he was at the hospital suffering from severe intoxication. How can one person be at two places at the same time? For there are many other factors or circumstances that are so crucial when it comes to DNA and what happens after the time of the murder. There can be still questions even when the DNA process worked well and there was a match. “When presented with Mr. Anderson’s hospital papers, the prosecution struggled to explain how an innocent man’s DNA ended up on a murder man.” The answer was that the paramedics who transported Mr. Anderson to the hospital were the same people who responded to the crime scene when Mr. Kumar’s body was being

DNA Profiling In The Criminal Justice System

...Deoxyribonucleic acid, commonly known as DNA, is the carrier of genetic information and the building blocks of all organisms. It is also the building block for both the defense and prosecution in criminal cases. This paper will explore the history of DNA profiling in the criminal justice system. While it is a common misconception that James Watson and Francis Crick discovered DNA in the 1950s, it was actually discovered in the 1800s. The molecule now known as DNA was first identified in the 1860s by a Swiss chemist called Johann Friedrich Miescher. Johann set out to research the key components of white blood cells, part of our body’s immune system. The main source of these cells was pus-coated bandages collected from a nearby medical clinic....

Dna Profiling Research Paper

...DNA Profiling: Private and Personal Information The topic of ownership and sharing policies of DNA profiling results is a controversial topic amongst individuals, families, doctors, and employees. Individuals should possess ownership of their genetic information. From a legal, ethical, and social standpoint, it is wrong to force someone, unwillingly, into sharing their DNA. Socially, the release of one’s DNA may cause tension and angst between family members. Legally, it is unrealistic to assume that shared genetic information will always end up in the right hands. Many argue over who is legally responsible for test results. Aside from laws regarding doctor patient confidentiality, individuals should the legal owner of their results....

...Personal Application of Criminology Paper CJA/314 Version 2 Criminology 02-27-2011 Personal Application of Criminology Paper When a person is in a situation like this, they may have a million things going through their heads, sometimes not and they’ll just proceed with calling the Police. With this situation one can handle it in a few ways, first call the police, then proceed with calling the boy’s parents, and tell my son what happened. If one can find out why this situation came about, meaning why your son’s friend came into your house by using a break in tool such as a lock pick, finding out that information would be helpful to have. The first thing a person should do is follow out with the most professional steps for the well-being of the boy, but keep your best interest at heart as well by keeping yourself safe. It’s important the parents know that their child has been involved in a crime instead of them finding out in the worst way with him calling after they have booked him in his cell. However, another reason one should call the parent because of course they may have never known that they’re child was doing things like this, and they may be able to talk some great deal of sense to him that may make him see the light of what he was doing, and if he does, the parents can talk to the police possibly and prevent him from going to jail and let them handle it. If not and the boy has to stand in front of a judge for what he did and he gets convicted of it then, the boy...

John Jeffreys Research Paper

...British geneticist who developed techniques for DNA fingerprinting and DNA profiling that are now used worldwide by investigators to bring justice to perpetrators as well as to resolve paternity and immigration disputes. Jeffreys was born into a middle-class family in Oxford, where he spent the first six years of his life until 1956, when the family moved to Luton, Bedfordshire. He attributes his curiosity and inventiveness to having been gained from his father, as well as his paternal grandfather, who held ma ny patents. When he was eight, his father gave him a chemistry set, which he enhanced over the next few years with extra chemicals, even including a small bottle of Sulphuric acid. He says he liked making small explosions, but an accidental splash of the sulphuric acid caused a burn, which left a permanent scar on his chin (now under his beard). His father also bought him a...

Fingerprinting

...Stein June 24th 2012 Fingerprinting DNA fingerprinting, also called DNA profiling, applies a test to determine the unique DNA sequence that each person has for the purpose of identification. In the 1930s, police detectives found each person has different patterns on the tips of the fingers, and these fingerprints became the standard for identification. However, the finger patterns can be altered by surgery or other means. DNA within living cells is difficult to alter. Sir Alec Jeffreys at the University of Leicester invented genetic printing in the mid 1980s. The DNA profile is similar to a fingerprint, existing only for that person. Jeffreys coined the term DNA fingerprint and envisioned its powerful use. A single hair, a drop of blood, semen, or other body fluid can reveal the identity of a person. DNA fingerprinting is used for identifying people, studying populations, and forensic investigations. It is in the area of forensics and crime detection that DNA use is the most promising-- as well as the most controversial. The technology of DNA fingerprinting is based on a single assumption that no two people have the same DNA. The 3-billion-base sequence is made of four biochemical blocks or nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The base pairs produce more combinations or variations than there are humans. In DNA fingerprinting, scientists focus on a segment where sequences vary a great deal from...

Forensic Analysis Of DNA

...New Methods for the Forensic Analysis of DNA By Professor David S. Haymer I attended the lecture by Professor Haymer about new methods for the forensic analysis of DNA. Forensic science has long been used in the US legal system for classic fingerprints, lie detector tests and others. Even though the use of DNA evidence is relatively new, it has changed a lot about forensic science and how things are done. It’s changed the legal standards for use of forensics in the courtroom and the way the evidence is collected and preserved, and how police are trained to investigate crimes. DNA is considered to be superior in many ways to other forms of forensic evidence like fingerprints, hair analysis and serology tests. The only DNA forensic evidence...

Forensicscience

...1)Introduction; Crime today is at an extreme high. However, forensic science has been there to help solve every crime committed Forensic science is the scientific method of gathering and examining information about the past. The word forensic comes from the Latin forēnsis, meaning "of or before the forum. The word forensic basically means the key to solve a crime.This is the technology used to help forensic teams to analyze and solve crimes.- This is especially important in law enforcement where forensics is done in relation to criminal or civil law,[1] but forensics are also carried out in other fields, such as astronomy, archaeology, biology and geology to investigate ancient times. Forensic Science is used to Identify Criminals Rape, murder, theft, and other crimes almost always leave a devastating mark on the victim. . In modern forensic science, the crime laboratories include photography section, Evidence storage section, identification section, chemistry section, General examination section, Fire arms section, instrument section and crime scene search section. 2)Origins of forensic science: In 16th-century Europe, medical practitioners in army and university settings began to gather information on the cause and manner of death. Ambroise Paré, a French army surgeon, systematically studied the effects of violent death on internal organs.[9][10] Two Italian surgeons, Fortunato Fidelis and Paolo Zacchia, laid the foundation...

Forensic Science: Genetic Analysis

...Analysis of DNA samples to identify individuals by characteristics of their DNA, known as DNA profiling, is used in forensic science to establish the guilt or innocence of criminal suspects, to identify victims, to determine paternity, and to contribute to basic research. The polymerase chain reaction (PCR) is used to replicate certain regions of the DNA sample. The short tandem repeat (STR) analysis is used to compare the length of STR sequences at specific sites in the genome. In the restriction fragment length polymorphism (RFLP) analysis, a DNA sample is cut into small pieces using a restriction enzyme, which are them separated by size and made visible on a gel. Population evolution, the generation-to-generation changes in a population’s frequency of alleles, can be used to estimate the frequency of a harmful allele, which can be useful in dealing with genetic diseases. Three examples of this evolution are genetic drift, gene flow, and natural selection. Genetic drift is a change in the gene pool of a small population due to chance. Gene flow is a genetic exchange with another population, which may add or remove alleles. In natural selection, the individuals with heritable traits suitable to the local environment generally leave more surviving, fertile offspring....

Steven Truscott's Wrongful Conviction

...Introduction 14 year old Steven Truscott gave his classmate Lynne Harper a ride on his bicycle on June 9, 1959. Truscott had dropped her off before they parted ways. Lynne was reported missing later that night, and two days later, her body was found on a nearby farm. She was sexually assaulted and strangled to death. The community was horrified by what happened to this young girl and everyone was determined to find the killer. Immediately, investigators became fixated on Truscott as the prime suspect since he was the last person to see Lynne. They didn’t consider any other suspects, even though there was no physical evidence linking him to the murder. He was arrested 24 hours later, and stood trial as an adult. (Steven Truscott | Murderpedia). The entire case was based on circumstantial evidence, and Truscott was found guilty and became the youngest person in Canada to be sentenced to death at the age of 14. The Crown’s theory was that Truscott committed the murder sometime between 7:15 and 7:45PM. The theory was supported by conflicting testimonies from child witnesses, testimony from the pathologist, Dr. John Penistan, and evidence on Truscott’s body (Harland-Logan). Four months after his conviction, Truscott’s sentence got commuted to life in prison. After spending 10 years in prison, Truscott was paroled in 1969, where he began a new life under a new name and started a family. This never changed the fact that Truscott had lost many of the good years of his life. Throughout...
