Forensic DNA Analysis is a multi-step process which starts with the collection of the DNA fragments, isolated from the crime scene, victims, suspects and other evidence. These DNA fragments can be biological materials like, blood, semen or saliva. The cell is then extracted from the nucleus by using a combination of chemicals and heat to release the contents of the nucleus which is where the DNA is stored. The selected contents from each DNA is then amplified, which means that specific regions in the DNA is copied multiple times. These fragments are then compared to other samples. Forensic DNA plays an integral part in solving crimes, determining paternity and identification.
In 1974 James Bian was convicted of the rape and murder of a 9 year old boy. James who was only 19 at the time was also convicted of burglary and kidnapping and was sentenced to life in prison. After spending 35 years incarcerated and after his fifth request to use DNA evidence to clear his name, in 2001 a statute was passed allowing cases to be reopened for DNA testing. The DNA evidence proved that James Bain did not kidnap and rape the 9 year old boy in 1974.

There is a wide variety of organisms present on the earth which is brought about by evolution of humans and the environment. This also includes the genetic variability and the diversity ecosystems. Biodiversity is important to and absolutely necessary for human survival and the provision of food, water. Most of the medicines comes from the natural rainforest which is home to a lot of the earths plants and animals. The earths biodiversity is being threatened by the destructions of the earth’s natural environment by habitat destruction, invasion of species, overexploitation and

    . DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique, there has been a large number of individuals released or convicted of crimes based on DNA left at the crime scene. DNA is the abbreviation for deoxyribonucleic acid.

  • Familial DNA Searching

    1418 Words  | 3 Pages

    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 samples. One of the more controversial practices of DNA forensics is familial DNA searching, which takes partial, rather than exact, matches between crime scene DNA and DNA stored in a public database as possible leads for further examination and information about the suspect. Using familial DNA searching for investigative purposes is a reliable and advantageous method to convict criminals.

    Christine Jessop was a nine year old girl who after bring dropped off by the school bus at her home in Queensville, decided to ride her bike to the park nearby to meet with her friends. After stopping to buy some gum at the local store, she was last seen walking her bike up her driveway by her friend Kim Warren. She did not keep her appointment with her friend at the park, and would never be seen alive again (Anderson & Anderson, 2009). This small town instantly became involved in the search for the missing girl, but with very little evidence to go on time passed, and hope began to diminish for the safe return home of Jessop. On New Year’s Eve 1984, eighty-nine days after Jessop went missing, her body was found badly decomposed in a bush by Fred Patterson fifty-five kilometers from Queensville. An autopsy would later revival that she was raped and mutilated (Anderson & Anderson, 2009). The police still did not have a suspect in the case nor did they have any leads, but now that her body was found the police and the small town were the topic of media, increasing pressure on the police to figure out what had happened to this little girl.

    DNA was collected from a small blood stain on Ms Lees’s T shirt which was located on the left shoulder and examined. The result produced a profile which was identical to the DNA profile of Bradley Murdoch. The forensic scientist stated that this DNA profile is at least 640 million times more likely if it had come from the accused than it had come from a non-related person selected at random. DNA evidence had a huge impact on the case because it linked the accused’s presence to the event at Barrow Creek.

This made proving the deaths on him would be a lot more challenging and would heavily depend on forensic evidence. One of the key victim’s in the conviction of Wayne Williams was 11-year-old Patrick Baltazar. When Williams was asked if he knew him, he said that he had never met Patrick. Some of the techniques they used were fiber analysis, DNA sequencing, and hair analysis.

  • Forensics in the Criminal Justice System

    334 Words  | 1 Pages

    The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the

    Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any Deoxyribonucleic acid (DNA) at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not too long ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones.

    Deoxyribonucleic acid (DNA) is an acclaimed extraordinary discovery that has contributed great benefits in several fields throughout the world. DNA evidence is accounted for in the majority of cases presented in the criminal justice system. It is known as our very own unique genetic fingerprint; “a chromosome molecule which carries genetic coding unique to each person with the only exception of identical twins (that is why it is also called 'DNA fingerprinting ')” (Duhaime, n.d.). DNA is found in the nuclei of cells of nearly all living things.

  • Use of DNA in Criminal Investigations

    2857 Words  | 6 Pages

    Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011). By analyzing this junk code, Jeffreys found certain sequences of 10 to 100 base pairs repeated multiple times. These tandem repeats are also the same for all people, but the number of repetitions is highly variable. Before this discovery, a drop of blood at a crime scene could only reveal a person’s blood type, plus a few proteins unique to certain people. Now DNA forensics can expose a person’s gender, race, susceptibility to diseases, and even propensity for high aggression or drug abuse (Butler, 2011). More importantly, the certainty of DNA evidence is extremely powerful in court. Astounded at this technology’s almost perfect accuracy, the FBI changed the name of its Serology Unit to the DNA Analysis Unit in 1988 when they began accepting requests for DNA comparisons (Using DNA to Solve Crimes, 2014).

    Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
