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…

Forensic science still has a long way to go before it can be considered as a science of high degree of certainty. Although it has been beneficial to a certain extent especially with regards to DNA forensics technique which, I will be discussing further in this essay. It nonetheless, has significant implications, forensic science is prone to errors due to analytical and structural defect. Furthermore, most crime labs are not accredited, although there is a choice of being accredited it is not…

Fingerprint evidence is highly accurate in the identification of suspects, because the likelihood of two different people possessing the same set of fingerprints is estimated to be one in 64 billion (Hall, 2015). Therefore, state and federal courts universally accept fingerprint evidence during a criminal trial due to the validated science behind the analysis of fingerprint characteristics (Hall, 2015). Next, as with everything else in law enforcement, computers have advanced fingerprint…

My primary interest of study lies in the field of forensic anthropology, in which I will analyze human remains while using a variety of techniques based on forensic chemistry to solve criminal cases. Moreover, forensic chemistry is a field of study that inspires my passion for science, while readying me for a future career as a forensic anthropologist. Ultimately, being an attendant at the Summer Pre-College Forensic Chemistry program at UMass Amherst will allow me to study a field that…

During the 10 through 24 weeks of gestation , ridges form on your epidermis, which is the outermost layer of skin on your fingertips. This pattern on your epidermis is known as your fingerprint. Fingerprint patterns are static and don’t change with age so an individual will have the same pattern from infancy to adulthood. Your fingerprint never changes over time, they will get bigger over time , but will not change. Fingerprints can be very helpful in identifying people. The FBI and many…

The past decade has seen great advances in a powerful investigation tool: DNA. Being DNA is found in every human being, every person's DNA pattern is one of a kind and except for identical twins, no two people can share the same DNA pattern. During a criminal investigation when biological evidence exists, DNA evidence can be used to identify criminals with incredible accuracy. Likewise, DNA can also be used to dismiss suspects or exonerate individuals mistakenly convicted of a crime. Ultimately…

What are the benefits of forensic science? Why is the application of forensic science in courtrooms beneficial? Can forensic science further lead to less cases where innocent people are put into prison for something they did not commit? It is said that "Since 1989, there have been tens of thousands of cases where prime suspects were identified and pursued—until DNA testing proved that they were wrongly accused" (Innocence Project, 2016). It is time, at last, to speak the truth about forensic…

This use of the Frye standard determines if the evidence or scientific testimony is generally acceptable in the scientific community. The Frye standard was used to prove that the peoples motion to use the scientific testimony for the lab tests conducted from the samples taking from the defendants watch was not admissible because of the unaccepted methods used by the scientists who had conducted the Deoxyribose Nucleic Acid test. This use of the Frye standard in the court case allowed the…

Otto Schneider Grade 10 Biology Ms Ruebe D Assessment - DNA Technology DNA Profiling Forensic Identification Forensic Identification refers to the use of forensic science to identify objects from trace evidence found on them. Trace evidence is used to reconstruct crimes or accidents. DNA profiling is a method in forensic science which can identify individuals by their DNA profiles. DNA profiles are encrypted sets of letters that represent a person’s DNA makeup. These sets can be used as a…

The Jefferson County Egan Murders took place on New Year’s Eve in 1964. The Egan family was found murdered at a rest stop on Interstate 81. The Egan trio consisted of Peter Egan, Barbara Egan, and Gerald Egan. This case was important to prosecute because the Egan’s were wanted for various crimes. Although the question remained, who murdered the Egan’s? Rumors and news media sparked many possibilities for what might have happened that night, which made investigators more eager to intervene.…
