Combined DNA Index System

DNA (deoxyribonucleic acid) is the genetic material that carries the genetic instructions being used in growth, development and reproduction of all living things. DNA has regions called genetic polymorphisms that are used to determine paternity/maternity, kinship, determination of human remains, and inherited diseases. DNA is an example of what forensic use for evidence in a crime. Using regions in the DNA you can determine a “fingerprint” for an individual that can help in a crime, with this many forensic sciences has helped law enforcement keep track of offenders. During DNA fingerprinting just, a sample of blood or hair from the crime scene can be used to extract DNA from. Polymerase chain reaction is used to make copies of that STR region because they are being analyzed. Another…

be subjected to DNA testing” (NIJ, 2012). Forensically speaking, biological evidence represents the collection and preservation of materials that contain DNA (deoxyribonucleic acid), a cellular fingerprint that is unique to everyone (University of Leicester, 2016). Within the past 30 years, DNA testing gained notoriety as a reliable way of determining genetic relationships and source origins of any genetic material collected at crime scenes. Thus, the accuracy and success of DNA and its…

Bloody partial palms print on the tile floor. The unique ridge characteristics in a fingerprint are also used to identify a suspect. I could use the Automated Fingerprint Identification System to find matches to fingerprints found at the crime scene. 4. Small baggie of a white, powdery substance. I would send to crime lab to have a forensic drug analysis done to see what the substance is. The type of test that would be done is microcrystalline test, chromatography and or spectrophotometry. 5.…

N. Norazmi. "Forensic DNA Profiling and Database." Malaysian Journal of Medical Sciences 10.2 (2003): 20-26. July 2003. Web. 15 Oct. 2016. In the article “Forensic DNA Profiling and Databases” S. Panneer Chelvam and M. N. Norazmi give case examples to how DNA profiling is used in crimes and what techniques are used to identify the person. They start out talking about deoxyribonucleic acid (DNA) itself and explains that every cell in an individual 's body, with the exception of red blood cells…

The advancement of forensic science has progressed immensely since its conception. The contributions it has made for the legal system are immense. One such example are its techniques used to extract DNA during forensic cases. DNA is considered to be one of the most well regarded and highly assessed sources of information (Gershaw et al., 2010). Another important development used during investigations is CODIS or the Combined DNA Index System. This is a computer database funded by the Federal…

Foremost, the accuracy of any technologies used to identify, collect, and/or analyse evidence has a major impact on the outcome of a case. If a piece of evidence is improperly analysed, such as a contaminated DNA sample, then an individual could be wrongly accused. To avoid this as much as possible, only the most relevant and accurate of forensic technologies should be used. The techniques that are less accurate should merely be used as an extension of the data found by more precise technologies…

Every cell in an individual’s body contains a full genetic program that gives that individual their own genetic identity. This contributes to genetic testing and how individuals can be identified today. One of the first known DNA identifications was in India in 1193 where Jai Chand, a great Indian monarchy, was destroyed by Muhammad’s army and Jai Chand, Raja of Kanauji, was murdered and he was then identified by his false teeth (Balachander, Babu, Jimson, Priyadharsini, & Masthan, 2016, p. 3).…

with homicide killing victim Taylor Thomas, a former college student. Bryan Bridges was originally proved to be at the scene when they tested a hair strand found on a hat left at the apartment in the room Thomas was found dead in. The hair after being tested on databases, like CODIS, in the KBI labs was then again looked at by a genealogist and was found to belong to Bryan Bridges. CODIS is a nationwide program developed for DNA samples to be scanned and uploaded. The system organizes all…

Forensic DNA is the process of using and collecting DNA from crime scenes to solve criminal investigations and to ensure accuracy and fairness in the Criminal Justice System. DNA profiling has grown significantly in the past years and has been extremely useful in identifying suspects, criminals and other people involved in the crime. If the suspect is unidentifiable, DNA evidence is compared to a DNA database to identify the criminal. DNA testing has both advantages and disadvantages many of…
