    Since 1985, DNA profiling in forensic science has become very important in this virtual era of technology and in the world of science that solves both major and minor crimes. Small traces of DNA are considered in all circumstances from how the DNA was collected to fully obtaining the profile in its significant form. Traces of sweat, blood and semen are the most common type’s evidence found at crime scenes. There are several different methods for creating a DNA profile such as STR (Short Tandem Repeat), PCR (Polymerase Chain Reaction), Y chromosome analysis, Restriction Fragment Length Polymorphism (RFLP) and Mitochondrial DNA (MtDNA) analysis. All these types of methods are able to extract DNA from a chosen sample taken from a crime scene. DNA profiling is the information of how a sample is processed and analysed and a DNA profile must be created by collecting and analysing VNTR’s (Variable Number Tandem Repeats), these are unique sequences on the loci which is an area on chromosomes. Most DNA sequences in different people look too similar to tell apart whereas VNTR result in bands that are unique enough for identification of individuals.…

    DNA, or deoxyribonucleic acid, is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA. However, a small portion of DNA can also be found in the mitochondria and is called mitochondrial DNA or mtDNA. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, kind of like the way in which letters of the alphabet appear in a certain order to form words and sentences.…

    “In 1986 DNA was first used in a criminal investigation in england (hirby, https://www.thelawdictionary.com).” “One year later, DNA was first used in the USA in Florida (hirby,james https://www.thelawdictionary.com/).” “In 1985 a professor at the University Alee Jeffrey’s was able to validate the uniqueness of personalized DNA material in each person's skin, body fluids, blood, nails and hair (hirby, james https://www.thelawdictionary.com/).” Once DNA testing was used to convict criminals law enforcement and criminal evaluation laboratories saw DNA technology as a major aid in being able to isolate accused or alleged suspects. Before DNA was available to use in crime investigations the law enforcement depended heavily on fingerprints, blood,…

    The discovery of the structure of DNA opened the realm of DNA technology which changed the way crimes can be solved. In order to understand the importance of DNA in a crime, the structure of DNA needed to be revealed first. One of the most important discoveries in history was the discovery of the structure of DNA by Watson and Crick in 1953 (Liras, 2008). This remarkable molecule contained genetic information that can be highly useful in solving a crime. DNA is the basic unit of life. The molecule uses the arrangement of bases and forms into a double helix. This arrangement contains information and instruction for the development of the body. DNA defines each of our individual characteristics therefore making it very unique. The “arrangement of these bases in each DNA molecule is different for everyone except identical twins” (Wilson, Foreman &ump; Asplen, 1999) and this is the key to the importance of DNA evidence. DNA is everywhere in the body and remains the same and that makes DNA a very important biological evidence. The individualistic characteristic is a key feature of DNA that assists in solving a crime. No one can deny or alter their DNA since it is found in every aspect of the body. Therefore it would be difficult for someone to defend the fact that the DNA is not his since DNA is very specific.…

    Science has become a very valuable tool for law enforcement. scientific evidence is used every day in criminal and civil courts throughout the United States; helping to Solve particularly difficult cases where all other investigative techniques have failed, provide clues where there are no witnesses, reduce the number of wrongful arrests, increase the reliability of evidence. Link together cases that otherwise could not be connected, such as local cases ranging from breaking and entering to homicide, multijurisdictional cases such as gang crimes, serial sexual assaults or murders, and major international investigations. DNA profiling can also be used effectively to convict the guilty and exonerate the innocent. Since the introduction of DNA evidence, it has played a key role in the investigation of numerous crimes; police now rely on DNA analysis to provide intelligence that was previously unavailable. The compelling evidentiary value of this technology has resulted in an increased expectation of impartial scientific evidence in the courts. It has been used as a part of impartial reviews of post conviction cases, and its convincing discriminatory ability has been instrumental in demonstrating support for exonerations and convictions alike.…

    When it comes to investigating crime, no matter the level of severity, nothing is more valuable to a criminal investigator than the use and implementation of forensic science. The results of such forensic investigations can be the difference between acquittal and conviction in a court of law. The single best aid that forensic scientists use is DNA, which has proven to be a powerful tool in the fight against crime. DNA evidence can identify suspects, convict the guilty, and exonerate the innocent. Throughout the Nation, criminal justice professionals are discovering that advancements in DNA technology are breathing new life into old, cold, or unsolved criminal cases. Evidence that was previously unsuitable for DNA testing because a biological sample was too small or degraded may now yield a DNA profile. Although DNA is not the only forensic tool that can be valuable to unsolved case investigations, advancements in DNA technology and the success of DNA database systems have inspired law enforcement agencies throughout the country to reevaluate cold cases for DNA evidence. In the next few pages I am going to talk about the importance of forensics in criminal investigations and how the two are tied together.…
