DNA FINGERPRINTING Background Reading - Nelson Biology and Campbell Biology Purpose - To understand the basics of DNA fingerprinting used in the Canadian courts for crime convictions and paternity suits. Introduction The process of DNA fingerprinting was developed by Professor Alec Jeffreys at Leicester University in 1984 as a form of genetic analysis. It was first used in the law courts of England in 1987 to convict a man in a rape case. It has now been used successfully in many crime and paternity

durability from the products they buy. Not only do they expect these products to perform well‚ but they want the finish to look good and resist corrosion for a much longer period of time. Powder coating is different from painting. There are no liquids or solvents. Therefore‚ it is the ultimate coating for environmental friendliness. Being dry‚ the powder overspray can be reclaimed for very high application efficiency. It uses heat to convert its state from a powder to a continuous film. The powder coating

Germ Line Control of female Sex Determination in Zebrafish In order to identify the sex of a developing embryo‚ many scientists have studied this process called sex determination that allows them to have better understandings on how sex is being determined in either vertebrates or invertebrates. Sex determination is normally determined genetically; however‚ other factors can contribute to its determination. There are numerous determinants that control sex determination‚ but the most important are

Germs‚ such as bacteria and viruses sometimes enter the body. When this happens‚ the bacteria or virus attack the body’s cells and begin to multiply. When this happens‚ it is known as an infection which in turn make people ill. Our body uses its immune system to fight of the infection that has began spreading in the body. Vaccines are used to help our immune system develop an immunity by imitating the infection. This means that there is a small amount of the bacteria or virus introduced to the body

DNA profiling is a method of identifying an individual by unique characteristics of their DNA. A specific DNA pattern‚ called a profile‚ is obtained from an individual or a sample of tissue. This allows the comparison of the base sequence of two or more DNA samples to determine whether they are related. DNA profiling has many uses‚ in prevention of economic fraud‚ dietetic work‚ and classifying species‚ identifying bodies‚ forensic science‚ screening for disease‚ and investigating paternity.

Extraction and Sublimation of Caffeine from Tea Leaves By: Ashley Barnes CH 236 – P8 Experiment 4 & 4.5 Due: 10/15/2014 Table 1. Table of Reagents Discussion The extraction yield refers to the percent of caffeine in the tea leaves at start of the extraction experiment. Tea leaves had 0.55 grams of mass per eight ounce serving. The weight of the extracted crude caffeine was 0.264 grams. Therefore‚ the extraction yield was 48%. This means that we pulled out almost half of the caffeine
