The National DNA Database - Is It Worth the Risk? In the past decade, genetic testing has become increasingly popular. Private companies, such as 23andMe have made genetic testing more accessible to the public, and allowed people to trace relatives and construct family trees and detect their susceptibility to disease. The improvement in DNA analysis technology and forensic DNA databases have also helped police to convict criminals charged with rape or homicide. However, it is not a good idea to
compare new samples of Deoxyribonucleic Acid (DNA) against the registered DNA samples of “convicted offenders, unsolved crime scene evidence, and missing persons across local, State, and national databases” (Office of Justice Programs, 2011). Scientific and government research identifies the program’s efficacy is a result of the increasing number of criminal case closures from cross-referencing suspect DNA samples against samples in the DNA database. Alternately, there is equal concern for the efficiency
Introduction The concept of DNA testing has expanded throughout the last several decades, and attention needs to be paid to the methods and implications of storing and using the samples. The human genome is a complex structure comprised of billions of base pairs. Only 0.1% of DNA makes up all of the differences in humans’ physical appearance (Pattock, 2011, p.855). Each person has about one hundred trillion cells, all of which contain chromosomes that make up an individual’s genome. DNA from a Chromosome
2005). Mitochondrial DNA (MtDNA) is inherited from the mother and passes down from female generations. For that reason, molecular biologists are able to link DNA from one person to a relative. I found it peculiar that albeit this specific genetic material is located in the mitochondria, which are housed within the eukaryotic cells and those cells have been reported to contain mostly introns; non coding sequences, this would be a reliable source for DNA. Issues surrounding DNA evidence and whether
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
DNA profiling is used in a variety of ways, such as establishing proof of paternity, or identifying siblings. While DNA contains material common to all humans, some portions are unique to each individual; thus, DNA testing can help solve crimes by comparing the DNA profiles of suspects to offender samples. DNA profiles can be used to identify individuals, allowing evidence to be used both as a means of convicting the guilty and as a means of exonerating the innocent. People can leave traces of their
doubt national DNA databases have proved useful in criminal investigations (Wallace, 2006, pS27). The concept of a national DNA database has raised concern about privacy and human rights as seen through the scope of public safety. All of these concerns are elevated with databases include convicted, arrestee, innocent, and “rehabilitated” offenders (Suter, 2010, p339). Robin Williams of University of Duham (2006) asserts that: “The rapid implementation and continuing expansion of forensic DNA databases
DNA analysis has come a long way since the beginning of any type of testing. Before DNA analysis became was used, or even used a widely as it is now, it was harder for law enforcement agencies to identify suspects of crimes. Now DNA analysis testing can determine the DNA of an individual, or a family member. DNA analysis is the process in which genetic sequences are studied. There are several different ways to analyze forensic DNA. This has had a great influence on the accuracy and reliability
The Bodies Are Talking: Will Society Listen? On Thanksgiving evening, November 27, 1992, Sergeant Kenneth Mathison and his wife Yvonne drive their 1988 tan Ford van along Route 131 in Hilo, Hawaii. The rain is pouring down and before he knows it, Kenneth Mathison is awaiting police assistance as he cradles his wife’s dead body in the back of their van. Mathison, a sergeant of 25 years with the Hilo Police Department was allegedly informing his wife, a maternity nursing professional at the Hilo
Negative Effects of DNA Profiling Genetic engineering has developed and blossomed at a frightening rate in the last decade. Originating as merely an area of interest for scientists, genetic engineering has now become an area of which all people should be somewhat knowledgeable. DNA profiling has many uses, both positive and negative, in our society. Aside from its usefulness in many legal investigations, DNA profiling can be used
Introduction DNA testing has been the center of attention in many criminal justice cases. The United States corrections centers have utilized the DNA testing process. Seventeen death row inmates have been exonerated by the use of these tests. Earl Washington was convicted of rape and murder in 1984. Although he confessed to the rape, he was also diagnosed as being mentally retarded. In October of 2000 Mr., Washington was given a DNA test and was excluded as the rapist and murderer. The Virginia
In the criminal justice system, the best chance of a fair trial and justice lies within cases that include physical evidence. Physical evidence, whether fibers, fingerprints, or DNA, can give a jury proof beyond a reasonable doubt. Physical evidence can convict a criminal, or it can free an innocent man. It can bring closure to families and to the law enforcement that work the cases. The following cases will show what physical evidence does in a criminal trial and the vast impact it can make. For
Should DNA Evidence be Admissible in Murder Trials? “In matters of truth and justice, there is no difference between large and small problems, for issues concerning the treatment of people are all the same”.(Albert Einstein).Many people have different points of view of what is justice of what happens in the courtroom. Opinions have been heard of whether or not DNA evidence should be admissible in murder trials. Not only have people try to introduce this kind of evidence in their case, but some have
acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore, the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell, Krauss, Liberman, Miethe, 2008). This paper examines Carrells et al’s research along with three other research articles to review how DNA is

cousin, they declined the adult male however agreed to help her look. This was the last time anyone saw Hamilton alive. Hamilton’s body was found to have been raped, strangled and beaten with a rock. The police collected a boot print at the scene and DNA that was found in Hamilton’s underwear. The police also relied on the witness testimonies and line-ups, which in this case was the photo array. With the five eye witness testimonies and a tip the believed to be suspect was found. Kirk Noble Bloodsworth
It’s raining. The drops trickle down the side of the window wall while some roll into the hut, but are too blurred for Sanjay to watch each one as it rolls down. He is much more aware of the drops he feels gliding down his own face, rolling off of his eyelashes, giving him a salty taste on his lips. His collar is wet, yet there is not one thing he can think about but his brother. He can’t stop thinking of yesterday. He still remembers the look on his brothers face as he lowered his eyes to the ground
Lynn Beslanowitch, a 17 year-old prostitute who died from head wounds in 1995 along the Provo River, Utah. It evaluates the type of forensic science technology used - touch DNA and M-Vac wet vacuum – before going on to look at how this new technology was used in the case. This essay explores the role forensic science and DNA analysis played in solving the case, leading police to the killer Joseph Michael Simpson, a convicted felon who was on parole at the time of the murder.

There was no indication that he had been inside¡Xexcept, for DNA evidence. The DNA test determined that similarities between sections of DNA removed from David¡¦s blood and DNA recovered from semen in Ms. Heggar¡¦s house would occur only one time in a total of 96 million people. On the evening of Ms. Heggar¡¦s death she was alone in her house. Eddie Ray Branch, her grandson
Ever since I was young I loved watching documentaries. I was fascinated by how criminals are eventually caught and drawn in to understanding how that was possible through techniques that include DNA profiling, analysing fluids and tissue samples for traces of drugs and poison. I was led to Forensic Science as a profession as it would combine my academic interests for understanding the genetic make-up of organism in general, with my need to investigate crime through rational, practical and valid methods
