DNA Extraction from Wheat Germ and 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

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 is a technique used in the laboratory to separate macromolecules such as nucleic acids and proteins. Electrophoresis can take a mixture of macromolecules of different molecular weights‚ shapes‚ and various electrical charges to determine all the various compounds in the mixture and allowing for further purification that can aid in details of individual elements of the mixture being studied. Agarose gel electrophoresis is a very important technique used in the field of

Function 16 October 2014 Gel Filtration and Electrophoresis Objective The essential goal of the experiment was to separate proteins in a solution based on size in different fractions. The relative protein content for each one fraction was found through the utilization of an amido black-based protein assay. Later in the trial polyacrylamide gel electrophoresis was utilized to separate BSA from hemoglobin. Methods I. Gel Filtration and Protein Assay: 1. A slurry of Bio-Gel P-100 beads in water was

to amplify DNA fragments using PCR (polymerase chain reaction) and then separate the products on the basis of size using agarose gel electrophoresis in an emulation of DNA fingerprinting. The task‚ which was successfully carried out was to determine whether DNA from suspects A‚ B or C matches the sample of blood found at the murder scene (X). The process of PCR acts in the same way as DNA replication but is restricted to specific DNA samples of interest. By amplifying the necessary DNA sequence‚

DNA DIGESTION AND ELECTROPHORESIS In this experiment we will be doing a process called as DNA digestion or also known as restriction digest. A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation‚ scientists Hartl and Jones describe it this way: This enzymatic technique can be used for cleaving DNA molecules at specific sites‚ ensuring that all DNA fragments that contain a particular sequence have the

The PCR is used to amplify the several DNA samples and gel electrophoresis is performed to separate the DNA fragments according to their size. [6] In the first part of the experiment‚ PCR amplification of the DNA templates was performed and the products obtained were used to perform gel electrophoresis. The process of PCR allows for the amplification of the DNA samples and the components needed to perform PCR are template DNA‚ DNA

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 that was collected

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
