Dna Purification Lab Report
To purify the PCR amplicon, both digested wt-goi and mut-goi from other components. A purified digested gene product is more advantageous for the DNA ligation, in which the gene products with sticky ends will be inserted to a plasmid vector. Also, to transform E.coli DH5α cells by introducing the plasmids DNA which contains the gene of interests into the E.coli strain(DH5α). The plasmid DNA can replicate inside the transformed E.coli DH5α cells, only successful transformed cells can produce the protein that is resistance to kanamycin, this allows for the selection of successful transformed cells.

2. Overview of experiments
DNA purification
Maintain the PCR volume of 50µL-100 µL. Pipet the elution buffer in the center of the PureLink®
Spin Column (PSC) and perform an incubation. Add B2 to PCR reaction. Add this sample to the PSC. Centrifuge the PSC. Replace the PSC into the wash tube. Add W1 with ethanol to the PSC. Centrifuge the PSC to remove any residual W1. Place the PSC in an elution tube. Add E1 or distilled water to the PSC. Incubate and centrifuge the PSC. The recovered elution volume should be around 48 µL. Keep the DNA sample in ice. After this step, a purify DNA sample should be obtained.

    For this type of experiment, we would generally see a decreasing trend for the total activity, total amount of protein, and percent yield and an increasing trend for specific activity and fold purification. These trends come about naturally when performing multiple purification steps. To determine the success of each purification step, the more important factors to look at are the total activity units, total protein amount, and percent yield.…

    In brief, the purpose of this lab was to isolate DNA from a food sample, amplify the DNA using a polymerase chain reaction, and test the amplified DNA for the presence of the Bt gene or the 35s promoter. In part one of DNA isolation, the food sample was crushed before Lysis Buffer was added, in part to break down some cell walls, but also to increase area of the food sample being touched by the Lysis Buffer. The purpose of Lysis Buffer is to break down the cells in the food sample and release their DNA into the solution. By increasing the surface area to volume ratio of the food sample, this process is accelerated. After the initial Lysis Buffer addition, the mixture was further ground to increase the contact between the food sample and the…

    1 µl of Taq polymerase and dNTP as well as 30 µl deionized water were added. For the second tube, 2 µl of JOSH04 (forward primer) and JOSH05 (reverse primer), 4 µl of genomic DNA, 20 µl of 5x Taq reaction buffer, 8 µl MgCl2, 2 µl dNTP mix, 2 µl Taq polymerase enzyme, and 60 µl deionized water were added. Amplification took place at 95⁰C for two minutes for one cycle (initial denaturation) followed by the next three steps happen in thirty cycles, denaturation at a temperature of 95⁰C for one minute, then annealing at 58⁰C for one minute, and extension for two minutes at 72⁰C. At 72⁰C the final extension happens for five minutes at for one cycle. Gel electrophoresis was performed using 1.0% agarose gel electrophoresis, made with TAE and 5 µl of Sybr safe. The PCR products were mixed with loading dye, pipetted at 10 µl and the gel ran for thirty minutes at 110…

    Also set up the filtering apparatus (see figure 1). Next blend 125g of Strawberries; Measure our 100mLs of the strawberry mixture and mix in 100mLs of distilled water, then put the mixture into the filtering apparatus, and leave to filter place filtrate mixture into a beaker. Fill a large beaker with hot water and place the smaller beaker inside (see figure 2) until the mixture is heated to 65°C. Take out the mixture and stir in 1gram of salt, 1g of meat tenderiser and 1mL of detergent. Pour 5mL of the now filtered and heated mixture into each of the 3 test tubes. In test tube 1add 5mL of methanol gently and slowly down the inside of the test tube. In test tube 2 add 5mL of ethanol. And in test tube 3 add 5mL of isopropyl. Allow for the DNA to precipitate and observe what is occurring. Once the DNA has precipitated it will look like cottony fluff in the alcohol or mixture. Collect the DNA using a wooden cocktail skewer, and place in labelled and sealed containers with 1mL of water and store in a fridge (at 4°C). Record each amount extracted. Repeat the method three times then run through a 1% agarose 1x TAE gel. All results observed should be recorded in a…

    DNA replication mechanism is an integral and the most important part of cell division. It is a complicated mechanism that requires a lot of steps and different enzymes. Many scientists were trying to understand the mechanism of DNA replication and its role in the transfer of the hereditary information to the offsprings. DNA replication begins with a single origin of replication that starts off the process by creating a replication bubble. In many eukaryotic cells, the DNA strand will have more than one origin of replication and, to speed up the process, the forming bubbles fuse together. By looking closely at the mechanism, one can identify a replication fork and many enzymes that play important roles in producing new double helices in the…

    The purpose of the DNA extraction lab was not only to inform students on how DNA is present in humans and all organisms, but to also educate them on how DNA can be extracted using common household materials. Also, the lab was very efficient as it introduced the students to extracting their own DNA found on their cheek cells as well as letting them take an observation on how DNA appears or how it is formed. Additionally, students were instructed through a very clear and simple procedure, which guided them into getting results. Moreover, students were able to acknowledge how their DNA found on cheek cells can be discoverable to them by following such uncomplicated steps, as chewing on their cheek, swishing saline solution in their mouth for a…
