    • 2 Pages

    DNA Gel Electrophoresis Electrophoresis is a process in which macromolecules are separated by utilizing their electrical charge and size. A technique for separating protein molecules of varying sizes in a mixture by moving them through a block of gel, as of agarose or polyacrylamide, by means of an electric field, with smaller molecules moving faster and therefore farther than larger ones. Gel electrophoresis of DNA is used in DNA profiling. When DNA is found at a crime scene, it's sent to a investigation lab. The DNA is extracted from cells and run through gel electrophoresis. Samples of DNA are also taken from suspects and run through the same process. When pieces of DNA line up, investigators know they have a match and…

    under such condition. Another reason could be that the cell did not get enough heat shock, or not enough pre-incubation time with CaCl2, which means the bacterial cell wall was not permeable enough for the DNA to come inside and interact with the bacterial DNA. The DNA gel electrophoresis showed that there were no fragments…

    Agarose gel electrophoresis of DNA is used to seperate mixtures of protein and nucleic acid fragments. Molecules tend to differ in size, charge, and mobility. The objective of this procedure is to predict the distance of DNA migrating towards the positive electrode in the electrophoresis chamber. Many scientists use agarose gel electrophoresis to examine the DNA of criminal suspects. The first step in this procedure is to prepare a buffer containing 1% of the liquid agarose gel. Once the gel…

    To examine the DNA, a gel electrophoresis test needs to be run. The first step of gel electrophoresis is to set the gel, which is made of agarose. Agarose is used to separate DNA molecules, and acrylamide is used to separate proteins. The gel starts off as a liquid, which is poured into a molding tray and after it sets, it will turn into a solid. Next .all of the DNA needs to be collected and copied with a Polymerase Chain Reaction, PCR, which is vital to the success of the gel process because…

    RESULTS Transformation: the transformation of the ade2 gene to the kanamycin resistant gene (ade2::kan2R) cause the cell to become red and grow on mediums containing G418 or kanamycin resistant mediums was observed to have occurred. PCR and Gel Electrophoresis: Figure 1 is the product of gel electrophoresis containing the wild type and transformed PCR products, either being or not being cut by HindIII. From the left (reader’s left) of the gel to the right the lanes are; 1.Ladder, 2. transformed…

    Agarose Gel Electrophoresis Since the discovery of the four classes of macromolecules (proteins, lipids, carbohydrates, and nucleic acids), researchers and biochemists have fine-tuned methods that reveal structural information about each of them. Different structural properties determine different functions and chemical properties, and scientists have developed intricate techniques to observe, quantify, and isolate molecules based on their aforementioned properties. Agarose gel electrophoresis,…

    surface of the tablet swells to form a gel layer which exhibits a gelatinous shape (Wilson and Crowley, 2011). This gel layer formed will govern the rate at which drug is released from the tablet (Shah, Chaudhary and Mehta, 2014) and it can be concluded that drug release for hydrophilic tablets are governed by swelling of the polymer rather than erosion. But there is also another factor that affects release which is the rate at which hydration occurs, this factor is controlled by the structure…

    then placed under a stereomicroscope for analysis. Lighting for experiments is provided by a 1000 lumen LED lightbulb. Usage of an LED lightbulb ensures that minimal heat will be introduced to the device and the output of light remains constant, ensuring that all pictures are exposed to the same degree of lighting which is a requirement for effective image analysis. Once all of the settings have been in place fluid will be passed through the device and pictures of the system will be taken at…

    The Silica Gel

    According to Simon (2002) the silica gel is the most widely used absorbent and it is the stationary phase that is dominant in Thin layer chromatography, particles or molecules that are non-polar travel faster at the stationary phase and the molecules that are polar spend more time at the stationary phase and therefore this means that molecules that are non-polar travel larger distance on the TLC plate in comparison to molecules that are polar since the polar molecules stick to the polar…

    box contains cow serum which shows high mobility since it dyes all the way to the bottom with different bands through the gel. Lane 2 contained one dark band at the bottom of the gel. Lane 3 shows o dark band with low mobility through the gel. Lane 4 shows one band stained with medium mobility through the gel. Sample proteins 1-4 were separated through gel electrophoresis where the mobility of proteins is due to different size and pI. Even when the latter marker is barely visible in the gel, a…
