OUTLINE What is PCR and Gel Electrophoresis? • Polymerase chain reaction (PCR) is a technique which is used to amplify the number of copies of a specific region of DNA‚ in order to produce enough DNA to be adequately tested. This technique can be used to identify with a very high-probability‚ disease-causing viruses and/or bacteria‚ a deceased person‚ or a criminal suspect. • Gel electrophoresis is a widely used technique for separating electrically charged molecules. It is a central technique

AGAROSE GEL ELECTROPHORESIS Gel electrophoresis is a widely used technique for the analysis of nucleic acids and proteins. Most every molecular biology research laboratory routinely uses agarose gel electrophoresis for the preparation and analysis of DNA. We will be using agarose gel electrophoresis to determine the presence and size of PCR products. Background: Electrophoresis is a method of separating substances based on the rate of movement while under the influence of an electric field

forensic anthropologists ran a gel electrophoresis with DNA from Skeleton 3 and two missing persons‚ Julia Ly and Teresa Chen to help in DNA identification. This process would allow restriction enzymes to cut by a specific restriction site and run through the gel‚ where the DNA fragments would move from the negative side to the positive side of the gel due to the negative charge of the phosphate group in DNA. The smaller the DNA fragments‚ the further they move down the gel. As mentioned above‚ the DNA

Enzymes and Electrophoresis Bhumik Patel Phillips 1/16/11 Restriction enzymes are tools in DNA research that can cut DNA into exactly needed pieces. Certain cuts can be rough‚ while others can be clean. Certain cuts can have an organized pattern to have a staggered cut. Other cuts will leave complementary bases with them. Electrophoresis allows the manipulation of DNA to separate and organize those parts. Electrophoresis is the substrate electric movement of the separation of DNA. Gel Electrophoresis

1. The central purpose of this paper is to describe all of the methods of how PCR was developed and the results of the experiments involving extraction and amplification of DNA (Mullis et. al. 1986). 2. PCR has the ability to isolate specific DNA sequences with the use of primers. This is done by denaturing the DNA (at 95o C) so it is able to anneal to the primers that specify a fragment to be amplified (Mullis et. at. 1986). These primes anneal to a specific sequence of DNA in order to amplify

Making an Agarose Gel AIM: To be able to make and agarose gel and perform gel electrophoresis in six different dyes. Also‚ to extract DNA from wheat germ. INTRODUCTION: Agarose gel is a substance that is used in science for gel electrophoresis and size exclusion chromatography. These processes use agarose gel to separate and analyze proteins and DNA. The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled into a gel. Agarose gel is most commonly

Title: Principles and Practice of Agarose Gel Electrophorsis Objectives: To detect the size ‚ shape and charge of the each dye solution. Methods: Casting the Agarose Gel In this experiment .8% solution was used. By using a 250ml flask the buffer solution was prepared. Using the equation to make enough solution for the intire lab class the equation had to be multiplyed by five. The contents of this equation were added to the 250ml flask and swirled to evenly distrubute it contents
