DNA profiling

The purpose of the previous study and results was to identify the possible perpetrator of the presented crime through blood analysis and match our forensic analysis with the characteristics and medical records of the missing person. In our blood analysis, we were given four samples of blood and the respective names of the suspects. In addition, Lowry police informed us that the second type of blood found, the one from the perpetrator, was O+. For this inquiry, our group hypothesized that based…

The Ethics of DNA Testing for Identification Following Arrest Abstract Following the initial realization that DNA could have law enforcement applications there was a tremendous rush to make use of the technology. This implementation was uneven both in its application and its acceptance, largely depending on whether the Daubert or Frye standard of admissibility of evidence during trial is used. More recently focus has been on some probably unforeseen uses of DNA evidence. Of particular concern…

Edmond Locard is a Frenchman who was the most important important contributor in forensic science. While studying medicine he developed an interest in law. During the First World War, Locard worked as a medical examiner with the French secret service in attempt to identify the cause and location of the soldier's death by examining the stains and damages of their uniforms. Later on, he finally convinced the Lyons Police Department to give him two attic rooms where he conducted research and…

The uses of Mitochondria DNA (mtDNA) is necessary in forensic because the DNA provides forensic science with valuable tools when investigating criminal cases, missing person’s cases and mass disasters (Sandhyarani, 2011; National Institute of Justice, 2013). MtDNA is a small double strand, circular molecule of 16569bp and it contain 37 genes located in a circular genome located outside of the nucleus. There are 2 rRNA, 22 tRNA and 13 polypeptides (Taanman, 1999; Webb, 2008). Most human cell…

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…

One of the advances in fingerprint evidence since Dr. King’s murder has been further study of the ridge comparisons (Saferstein, 2015). A person’s full fingerprint averages 150 ridge characteristics providing plenty of comparison for an identity match (Saferstein, 2015). There have been arguments made that prints collected at a crime scene are not complete, full prints and that could subject the comparison to be invalid because an incomplete fingerprint may only allow for a very limited number…

it both current and informative. It serves a great purpose providing various benefits. However, the use of technology can also raise some controversy. The advancement of DNA technology is imperative and it has significantly changed the legal system in the way cases are questioned, investigated and solved. On the other hand, DNA sampling raises issues involving privacy and the violation of human rights due to its personal, unique makeup and the fact that it is stored in a database. The…

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, DNA evidence is increasingly vital to…

translation genome-widely will provide and reveal what are the key players that are required for developmental competence and which of these are shortage in Hira mutants. I will take risk and develop/explore the feasibility on applying Ribosome profiling technology (using ARTseq) on mouse oocytes, which have not been conducted yet. The data will reveal the profile of active translation and further integrate with total RNA-seq data will uncover the translation levels. By comparing wild type…

of these defects and it is mainly due to the cause of having a genetic mix up (Miranda Hitti, 2006). This is where the human genome project comes to the rescue. The human genome project has a goal of achieving an "accurate sequence of the 3 billion DNA base pairs that make up the human genome and to find all of the estimated 20,000 to 25,000 human genes." (GHR, 2015). With this information, our medical technology can advance significantly…
