DNA Analysis Introduction When the forensic anthropologists gave the DNA Analyser their findings, there was a problem. The police gave the DNA Analyser all of the missing people in the St. Charles area within the past year and they matched the persons up with results from the forensic anthropologists. It appeared that there were two missing persons who had fit the description of an African-American woman that's in between the ages of 25 and 30 with a height range of 5 feet 0.9 inches to 5 feet and 4.7 inches. Since two people who have been reported missing in the past year fit the description for “Skeleton A” found in the park, a DNA test was going to be the best way to narrow them down to the people who were found at the park. Running the …show more content…

If one of the missing persons were identified as the skeleton found, then the family of that missing person would at least have some closure on what had happened to their loved one while the other would have to wait for some fortunate chance on another case. If it appeared to be that neither of the missing persons fit, then there’d be zero closure and even more question on who the skeleton belonged to and why were they there in the park. Running a test on “Skeleton A” is crucial for solving this case.

DNA Analysis DNA is ran through a process called gel electrophoresis in which DNA is cut up and ran through a gel where certain lengths of DNA become banded. This procedure can match a parent to offspring or compare missing persons to skeletons at a crime scene. In this case, “Skeleton A”’s DNA will be matched up to the two missing persons in the St. Charles area. The first step of gel electrophoresis is to create multiple copies of all the DNA (scientifically called Polymerase Chain Reaction) so if something goes wrong, it can be tested again and again. The next step involves digesting the DNA samples with restriction enzymes. In this DNA test, restriction

    Firstly, an amount of 40.90 g of NaCl was weighed using electronic balance (Adventurer™, Ohaus) and later was placed in a 500 ml beaker. Then, 6.05 g of Tris base, followed by 10.00 g of CTAB and 3.70 g of EDTA were added into the beaker. After that, 400 ml of sterilized distilled water, sdH2O was poured into the beaker to dissolve the substances. Then, the solution was stirred using the magnetic stirrer until the solution become crystal clear for about 3 hours on a hotplate stirrer (Lab Tech® LMS-1003). After the solution become clear, it was cool down to room temperature. Later, the solution was poured into 500 ml sterilized bottle. The bottle then was fully wrapped with aluminium foil to avoid from light. Next, 1 mL of 2-mercaptoethanol-β-mercapto was added into fully covered bottle. Lastly, the volume of the solution in the bottle was added with sdH2O until it reaches 500 ml. The bottle was labelled accordingly and was stored on chemical working bench.

    The analysis of the samples should be used only to confirm or negate match between the sample taken from the crime scene fgand the sample taken from the suspect. That is, it should sdfremain as an identifgication tool only. There should be no further analysis of the DNA to suggest psychological characteristics that would make the suspect more likely to have cdfommitted the crime. This rule should apply also to samples taken from convicted dfdoffenders for a data vor dagta bank.

    The show portrays that forensic anthropologists are responsible for almost every aspect of the death investigation, which does not correctly depict the role of forensic anthropologists (Wood,2017a). The method of which components of the biological profile, like sex of the remains, is also incorrectly portrayed as Dr. Brennan estimated the sex using a trait that does not accurately indicate sexual dimorphism (Wood, 2017c). Lastly, the complexity of personal identification, which is one of the most important aspects of forensic anthropology casework (Krishan et al, 2016), is not portrayed correctly as Dr. Brennan and her team based the identification of the remains on one trait that has questionable reliability (Charles & Levisetti, 2011). All in all, ‘The feet on the beach’ episode of ‘Bones’ does not accurately portray the forensic anthropology as it is romanticized for entertainment and overly simplified for a lay person to

    . 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.

    A DNA sample was then taken from the crime scene, Anna, and Erica to officially identify whose blood was found using gel electrophoresis. The restriction enzyme HaeIII, which cuts the DNA strand at the sequence GGCC, was placed into the samples of DNA and then ran through the gel. When the process was complete the crime scene DNA profile matched identically to Anna’s DNA profile with lines showing up at lengths 12, 23, 11, 33, and 24. After the conclusion of this experiment it was concluded that the blood found at the crime scene belonged to Anna

    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.

    It’s not everyday that you find some bones in the ground while walking your dog! As a forensic anthropologist who has just found some human remains lying around I would definitely decipher the biological profile, reconstruct the face, and testify in court to identify the unknown person. The job of a forensic anthropologist isn’t always easy, but by using these three steps, it shouldn’t be that tedious and hard.

    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. 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.

    When a suspicious body appears in the morgue, the forensics team goes to work. The body, if still covered in tissue goes to the forensic pathologist who will study the tissue extensively. If a conclusion is unable to be reached through this process, the pathologist will remove the tissue from the bone and send the skeleton to the forensic anthropologist. In other cases, the victim is found with no to little tissue on the bone, making it nearly impossible for a layman to discover any identifying characteristics about the person. The forensic anthropologist’s first job is to determine the sex, age and race of the victim (Sauer, 1998).

I had prepared for the highly competitive entrance exam AIET to get admission into the integrated Masters Degree in Biotechnology and Bioinformatics at Dr. D.Y. Patil University and secured 87th all over India rank and was proud to gain admission to this venerated university. The academic curriculum has introduced me to amazing subjects like ‘Microbiology’, ‘Molecular Biology’, ‘Biochemistry’, ‘Genetics’ and ‘Industrial Biotechnology’. Although many seminal biological events have been explained in theory during the past century, the technology to harness their potential for benefiting humankind has only been possible during the past few decades. This is testament to the great improvements in biotechnologies and I am glad to be a part of this grand scientific experience.
