Strayer University CRJ 320 Criminal Investigation Professor: Elaine Wilson The importance and legal uses of DNA evidence in Criminal Investigations Tasha L. Thomas 4/21/2013 Once a crime is committed law enforcement officers are dispatched to the scene and a criminal investigation begins immediately. The first responder to the scene begins to taper off the area and assures that nothing is touched or risk of contamination of evidence occurs‚ while waiting on the

forensic science. One specific area is that of forensic biology; the application of biology to law enforcement. This discipline has been used to solve crimes by matching crime scene evidence to suspects‚ identifying victims and determining paternity to name a few. DNA based techniques are a sub-discipline of forensic biology and are a crucial component in this field of work. DNA analysis began in the mid 1980’s and revolutionised the field of forensic science. With continual refinement of DNA analysis

Background on Genomic DNA Isolation and Purification Generally‚ all methods involve the disruption and lysis of cells. This is followed sometimes by the removal of RNA (by RNAses‚ salt or other methods). Choosing which method to use will depend on many selection factors including: DNA is isolated from proteins by several methods including digestion of proteins by the enzyme proteinase K. Proteins are removed subsequently by salting-out‚ organic extraction‚ or binding of the DNA to a solid-phase support

DNA Extraction from Fruit 1. What was the purpose of adding liquid soap and salt in step #1 and how does NaCl contribute to maximum DNA extraction. The purpose of using soap was to destroy the membranes inside a kiwi cell. Soap helped with that because it dissolves the membranes easily. Salt or NaCl was used to remove proteins and carbohydrates. NaCl caused the proteins and carbohydrates to precipitate. 2. Why was it necessary to “mush” the kiwi by hand? If the step was omitted‚ what

Ka Zhu The Importance of the Structure of DNA Understanding ideas at a macroscopic scale is simple. Looking at a clock‚ observing and understanding the movements of the hands over the numbered surface are‚ in essence‚ all one requires to use the device. In order for innovation to occur‚ it is imperative to understand the inner workings of the device on a microscopic scale to modulate its properties. Such is the case for many innovations in science‚ from the heat engine to penicillin‚ and is no

The Discovery of the Structure of DNA Determining the structure for DNA was one of the outstanding science achievements of the 20th century. It started in the late 1940’s‚ when scientists were aware that DNA was most likely the molecule of life‚ even though many were sceptical since it was so "simple." They also knew that DNA included different amounts of the four bases: adenine‚ thymine‚ guanine and cytosine (usually abbreviated A‚ T‚ G and C)‚ but nobody knew what the molecule might look like
