1.Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory (under "resources" at the bottom of the window), who is one individual that contributed to modern genetic analysis? What did this person contribute?
I would say that analyzing the blood in a lab would be the best technique. Alec Jeffreys is known as the father of genetic profiling. He invented what is now an essential technique, especially in forensic science, called a polymerase chain reaction, or PCR.
2.How are computers used in fingerprint analysis?
Experts examine tiny fingerprint details known as minutiae. These may be loops, dots, forks, islands, etc. Several comparison points must be perfectly matched for two fingerprints to be considered identical.
3.Who is a pioneer in fingerprint analysis? Describe a famous case that this person was involved in.
Edward Foster studied fingerprint analysis in the US and introduced it to Canada. IN1911, Foster testified as a fingerprint expert in the Jennings case. Fingerprints in the wet paint next to Mr. Hiller, the murder victim, were the only clue. Foster demonstrated to the court that the prints of Thomas Jennings, who had been arrested as he was fleeing the scene, matched those left in the paint, and Jennings was convicted.
4.What is the role of the forensic chemist in crime scene investigation?
These experts analyze all chemical, organic, and inorganic aspects of a sample. They separate the components and identify them using a variety of tests and devices. Their findings are used as evidence by the investigator and in court.
5.Who helped pioneer forensic chemistry? Describe one of her famous cases.
France McGill became a pathologist and teacher is Saskatchewan. When Dr. McGill examined the stomachs of an elderly couple who had died on Christmas Day, she found a large quantity of strychnine, a powerful poison, along with the bran. The murder

    Once the blood sample is isolated from all other organic material DNA is extracted from its biological source material using a hypotonic chemical buffer and being centrifuged. The extracted DNA is then measured to evaluate the quantity. After isolating the DNA, specific regions are copied with a technique known as the polymerase chain reaction, or PCR. PCR produces millions of copies for each DNA segment of interest and thus permits very minute amounts of DNA to be examined. The resulting PCR products are then separated. The separation methods used today include slab gel and capillary electrophoresis. Fluorescence detection methods have greatly aided the sensitivity and ease of measuring PCR-amplified samples. The specific methods used for DNA typing are validated by individual laboratories to ensure that reliable results are obtained and before new technologies are implemented. Samples are then compared to each other as well as DNA databases which are a valuable tool and play an important role in apprehending criminals that have committed a crime before.…

    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).…

    Advancements in forensics science and DNA technology has revolutionised our ability to solve crimes, subsequently helping to develop clear and concise investigative processes. The discovery of DNA and methods of identifying individual genetic imprints such as Familial Searches has allowed more sophisticated analysis which has advanced since the Colette Aram case. Identification of DNA is vital when identifying and convicting suspects or even exonerating individuals. Thus, having an accurate system of DNA identification has been an essential discovery of the 20th century (British Medical Association, 2012). This paper will examine the limitations encountered while investigating the Colette Aram case, subsequently analyzing the advancements that…

    “… [Galton] undertook the first definitive study of fingerprints and developed a methodology of classifying them for filing. In 1892, Galton published a book titled Finger Prints, which contained the first statistical proof supporting the uniqueness of personal identification. His work went on to describe the basic principles that form the present system of identification by fingerprints.” (Saferstein, pg. 8, 2009)…
