DNA Forensics in the case of Dindin
DNA Forensics in the case of Dindin DNA Forensics is the most accurate method of determining the identity of an individual but, like any other molecular biotechnology, involves a complicated process. As stated in www.forensicscience.org, “Through DNA testing, law enforcement officers are able to identify human remains or the individual responsible for a crime. DNA testing is a highly advanced scientific process that involves replicating the human DNA sequence to create a genetic map of an individual. Because of its reliability, DNA testing has become a significant factor in criminal cases.” DNA testing, or more specifically Parental testing, was the method used by the National Bureau of Investigation (NBI) to identify the body of Geraldine “Dindin” Palma. The process begins with extracting DNA from a tissue or cell, in Dindin’s case, extracting the DNA from her femur tissues, then amplifying this strip of DNA through the polymerase chain reaction. After, a restriction enzyme is used to cut the DNA into fragments which are separated through electrophoresis. Lastly, radioactive material is added to make these fragments visible. DNA testing will take at least 5 days to complete. These DNA fragments are compared to those of the parents’. If a parent is a biological parent of a child, the “probability of parentage” will be 99.99% and they are not related at all, will be 0%. In Dindin’s case, her mother, Felma Estravela, was found to have 99.99% probability of being her mother but interestingly, it was discovered that her father, “Gerald Palma,” was not her biological father. DNA testing is the most accurate and advanced method of identifying a body but is not entirely flawless. In Dindin’s case, it took two years to come to a conclusion because the large amount of formalin in the body made it difficult to extract DNA. Another instance, although rare, is when an individual possesses two different sets of genes which can cause the result to yield a 0% probability

    Lab 8: Genetic Analysis

    • 297 Words

    In Lab 8, we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis, it was determined that they did belong to a female. However, it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling, also referred to as typing and fingerprinting, uses genetic material to show relatedness and uncover the identity of organisms. Most commonly associated with forensics, it can be used in an array of scientific fields such as anthropology. One method that can be used, when a large sample present, is restriction…

    It has been approximately twenty months since 2001s September 11th terrorist attacks on the World Trade Center, and still victims' bodies are in the process of being identified. In matters like this, forensic scientists are forced to "bring out the big guns." Researchers can compare DNA samples from bodies to those taken directly from the victim: from hair, a toothbrush, a family member, and etcetera (Whitfield 6).…

    A sample of DNA found in a crime scene was provided along with five suspects. Their DNA was then processed using restriction enzymes and Agarose Gel Electrophoresis. The objective of this lab was to match a criminals DNA to a crime scene using restriction enzymes EcoRI and Pstl with Agarose gel electrophoresis. Restriction enzymes cut DNA at a specific base pair site recognized by the enzyme, which then turns one single strand of DNA into many fragmented strands of DNA. EcoRI recognizes and cuts the palindromic base pair sequence GATTC while Pstl recognizes and cuts the palindromic base pair sequence CTGCAG. Agarose gel electrophoreses separates these fragmented DNA by their size. The negatively charged DNA moves through the Agarose gel to the positively charged end of the gel. The smaller fragments move through the gel more quickly allowing a linear view of the fragmented DNA when the process is complete. Since each individuals DNA will be cut into different size fragments when restriction enzymes are applied we can match one of the suspects to the crime scene DNA sample. This process enables an individual’s DNA to be matched, much like a fingerprint, to a sample of unknown DNA.…

    The answer to that is DNA fingerprinting. DNA fingerprinting was actually found on September 10, 1984 on accident by a man named Alec Jeffreys in Leicester, England (Todayinsci.com). DNA fingerprinting has changed the world we live in. It is able to diagnose inherited disorders in adults, children, and babies (Todayinsci.com). It is also used to solve crimes, although the first time it was used in a criminal case, the guilty was proven innocent (Todayinsci.com). DNA fingerprinting is used to find missing or unknown family members (Todayinsci.com). This makes DNA fingerprinting a beautiful thing because it can reunite family members and solve…

    Like most technological tools, the accuracy of DNA testing can be subjected to human error. Whether a sample is obtained from a crime scene or taken from an individual there is always a risk. Although DNA is considered to be highly accurate when done correctly, the notion that DNA testing is “free from error” is wrong in both principle and practice. The fallibility was painfully in clear in 2003 when the Houston Police Dept. crime lab was shut down after an investigation revealed widespread problems of misinterpretation and mishandling of evidence by those personnel responsible for handling such evidence. Aside from human error, another that issue on the rise is the lack of sufficient and proper training of the personnel responsible for collecting the samples. Often times these individuals mislabel, or misinterpret exactly what it is they are sampling. An example of this was in 2003 when Josia Sutton was released from prison after serving four years. Members of the police laboratory convicted Sutton as a result of mistaken identity and faulty scientific…

    As dental pulp is surrounded by dentin and enamel, which forms dental armor, it offers the best source of DNA for reliable genetic type in forensic science.1,3,5,7 Teeth represent an excellent source of genomic DNA because of their resistant nature to environmental assaults such as incineration, immersion, trauma, mutilation and decomposition. The identification of individuals is not the only use for dental DNA. The technique has allowed criminal investigators to link victims to crime scenes once the body has been removed and incinerated.4,8 The identification of dental remains is of prime importance when the deceased person is skeletonized, decomposed, burned, or dismembered. Since natural teeth are the most durable of all tissues, they can persist even long after other skeletal structures have been destroyed by physical…

    Since the test involves taking only a small blood sample, where a person’s DNA can be found, these tests have a minimal health risk. Genetic testing was initially used in pregnancies to test for diseases like Down's Syndrome and other genetic disorders (“What are the...”). However, thanks to more recent improvements, genetic testing has come to display several weaknesses and strengths. The genes that can be obtained from infants can notify parents of possible physical deficiencies, while others may show physical advantages (Stein).…

    When collecting the evidence for samples of DNA is extremely laborious and also time-consuming. The likelihood of finding blood stain somewhere in the immense area is infinitesimally small (Laird & Blackmore, 2009). By spending too much time on small evidence will not only take up the time but also lead to failure of finding the suspect. In addition, DNA matching could only happen when there is a matching DNA in the database; however, for the data of 2010, there is no library contacting all DNA of people (National Forensics Science Technology Center, n.d). In addition, when samples have a very low amount of DNA, it could have been disturbed by environmental conditions or the undesirable way of preservation (Figarelli,…

    The use of DNA Technology in the Criminal Justice system has definitely become an integral part of the entire investigation process at a crime scene. When the law enforcement, crime scene investigator and forensic teams arrive their first priority is to seal off the area to prevent contamination of any evidence or DNA left at the scene. DNA left a crime scene can consist of any of the following blood, semen, skin cells, tissue, organs, muscle, brain cells, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine, feces, etc. It can be found anywhere at the crime scene, however in order to obtain a good sample the crime scene investigator and other law enforcement officers must maintain the highest standards for the collection and preservation of the DNA evidence. They must ensure that the DNA testing methodology meets rigorous scientific criteria for reliability and accuracy.…
