Lab Questions: Unit 1 Autopsy of a Crime Scene 1. Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory‚ who is one individual that contributed to modern genetic analysis? What did this person contribute? - The DNA Analysis Technique is the best choice because no two individuals have the same DNA. This makes it easy to determine a match between the person the blood came from and the blood sample. Alec Jeffrey’s came up with the first genetic profile

DNA typing was first used in Great Britain for law enforcement purposes in the mid- 1980s. It wasn’t employed in the United States until 1987. DNA profiling has changed forensic science. DNA technology has given police and the courts a means of identifying the suspects of rapes and murders. Today‚ the Federal Bureau of Investigation performs the bulk of the forensic DNA typing for local and state law enforcement agencies. In criminal investigations‚ DNA from samples of hair‚ bodily fluids or skin

Lab Report: Stoichiometry Lab Oct. 27‚ 2011 Claire Elizabeth Lab Partners: Hannah Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

Marissa Arias Senior Rhetoric Graf-8 April 14‚ 2014 Gel II Manicure Many women and even some men love to get their nails done‚ but hate how much time it takes to dry and on top of that they are extremely easy to ruin and chip. There is a new type of manicure trending know as Shellac‚ Gel nails‚ or No chip. According to my cosmetology instructor Samantha Rudman‚ this process takes about 35 to 40 minutes but dries in seconds. Many individuals would love to know this process even the men that

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating
Premium Chemistry Spectroscopy Ammonia
was synthesis by reacting concentrated hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques were used to get a pure product of t-pentyl chloride. The percent

Gel filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances
