Hypothesis: If I were to extract DNA without proper chemicals and equipment, the result DNA would become faulty or poor quality for further investigation
My hypothesis predicts that if we were to use improper or non-lab chemicals, the result DNA would become faulty and would result in an inadequate samples for further studies, it would seem that if we were to extract DNA without chemicals like lysis solution, concentrated salt solution, resuspenstion buffer, ethanol or isopropyl alcohol, it would result in poor DNA results.
Method one
Method one to create a perfect result and to extract the optimal DNA, I would believe that we would need centrifuge, sample tube, micropipettors, lysis solution, concentrated salt solution, resuspenstion buffer,

We can get these cheek cells by just brushing the side of our mouth with a slab, but before we get the cells, we must rinse for 30 seconds to remove all the extra food or any other unwanted subjects. After we rinse then brushed the insides of the mouth to get the cheek cells, we can cut the end of the slab and put it into a sample tube. The first step into extracting the DNA is to mix the slab with some lysis solution, using the micropipettor we can add the desired amount of lysis solution, after adding the solution using …show more content…
Such as a saline solution (salted water), a clean glass, 1 tea spoon (5ml) of detergent, 3 tea spoon (15ml) of tap water, a clean tea spoon, any type of cold alcohol (stronger is better – vodka or gin), and cheek cells or any type of saliva substance. Firstly, start rinsing with the saline solution for 30 second, this is to extract the cells within the mouth and also cells around the cheeks. Then continue to spit the saline solution into a mix of 5ml of detergent and 15ml of tap water, thus hopefully transferring you DNA to the solution. With mechanical agitation for the duration of 5 minutes, within this time frame the tissue of the cheek cell should begin to burst and worsen the cell membrane and things surrounding the nuclei, which would lead into releasing the DNA within the cell. Next, you can continue to slowly pour your cold alcohol into the mixture, because DNA is insoluble in cold alcohol, the DNA would slowly appear into white strains. With the cold alcohol, other compounds would dissolve and the DNA would slowly be separated from the other compounds and would be visible to the naked

    Purpose and Background Cells divide in two ways, mitosis and meiosis. Mitosis is used to produce cells that are genetically identical to the parent cell for growth, asexual reproduction, or repair after injury. Cells that are produced by mitosis are diploid, meaning that they have two complete sets of chromosomes, one from each parent. Meiosis is used to produce haploid cells that have only one set of chromosomes, a mix of chromosomes from both parents. Meiosis produces cells that are genetically unique from their parent cells.…

    The purpose of this lab is to examine cross sections from the leaves of C3 and C4 plants and to determine the morphological differences between them while relating those differences to their metabolism. In C3 plants the carbon dioxide is first incorporated into a 3-carbon compound. Their stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells.…

    Interactive Question 7.2 Cite some experimental evidence that indicates that membrane proteins drift. A good form of experimental evidence is Fluorescence Recovery After Photobleaching, aka FRAP. In the FRAP process, membrane proteins are labelled with a green fluorescent protein, and part of the plasma membrane is “bleached” with a laser, causing them to lose their fluorescence. The part that was bleached will eventually become fluorescent again, as molecules drift in by diffusion.…

    In the four-week long experiment conducted in the Bio 13 Lab, we were able to conduct a genetic analysis of the yeast S. cerevisiae, particularly investigating the inheritance and linkage of three genes: HIS4, LEU2, and LYS2. In week one, a suspension of spores was received and aliquots of the suspension were plates onto two YPD plates. After a week of yeast growth, haploid spore clones were carefully picked from the plates by sterile toothpicks and used to make patches on a new YPD plate, the master plate. In week three, the master plate was replicated onto three dropout plates: -His, -Leu, and -Lys. In the final week, the growth of the patches on the dropout plates were analyzed and class data was collected in order to conduct calculations for…

    The study of microbiology requires not only understanding the microscopic organisms, but also the understanding of lab techniques and procedures used to identify, control, and manipulate microorganisms. The identification of microorganisms is not only important in microbiology lab, but also in the medical field to identify an agent of a disease that will help treat the patient by using the correct antibiotics to kill off the host. In this unknown lab report, techniques and procedures learned in the microbiology laboratory during the semester that was performed to test ones practical understanding of microbiology. The sole purpose of the unknown lab is to demonstrate understanding of the experimental methods and lab techniques learned during…

    Discussion: My first hypothesis that the sepia eye and ebony body experimental cross would result in a 9:3:3:1 ratio, and that the traits would be autosomal, unlinked recessive, was found to be false. I chose to reject my hypothesis because my calculated test statistic, 587.5, was larger than the critical value, 7.815. The traits, ebony and sepia, are linked, seeing that they fit in 2:1:1 linkage ratio and that the recombinant number is smaller (Table 1.1). They are autosomal; the amount of males and females affected are relatively equal.…

    Then mordant is added, creating a crystal violet-iodine complex. The slide’s then rinsed with 95% ethanol until it turns clear and rinsed again with distilled water. A counterstain called safranin is used to stained the cell last. The method of gram staining will help determine whether the unknown is gram-negative or gram-positive. My unknown illustrates a purple colored stain in the microscope and it reveals a positively charged stain.…

    Separation of plasma proteins by molecular exclusion chromatography Sebastian Prisacariu 140013826 Introduction The components of blood is broken down into 3 parts. This breakdown is consisted of: Plasma which is a yellowish fluid that helps transport blood cells around the body and contains a small supply off proteins, platelets which are blood clotting agent, red blood cells which is a carry for oxygen and remover off carbon dioxide and white cells which is the bodies defence from infection. The plasma makes up about 55% of the overall volume of blood and is mainly made up of water which contains important proteins like albumin which maintains fluid balance (Nall, 2013) and globulin which serves as antibodies and helps with transport (Clinn,…

    In this experiment, a SDS-PAGE gel was used to analyze the protein samples from the MBP-AP and WT-AP experiments. The samples are then referenced to the ladder to determine the molecular weight of the MBP-AP and WT-AP proteins. Then the UV absorbance of the two proteins from 240 nm to 340 nm is determined using a nanovolume cuvette. The absorbance at 280 nm was then used in conjunction with data from previous experiments to determine the concentration of the MBP-AP and WT-AP protein samples. Results of experiments showed that the SDS-PAGE gel yielded expect bands and the approximate molecular weight of wild type alkaline phosphatase and maltose binding protein-alkaline phosphatase is 49 kDa and 95 kDa, respectively.…

    Then I rinse with water over the staining dish. Secondly, I will add Gram iodine (Mordant) for another minute, which then the cells will the form a crystal a complex with crystal violet then rinse off the stain. The third step is to add 95% ethanol 5-10 second if the bacteria are Gram negative it would the cell would look colorless for the and if it is Gram positive the color would remain purple. I did then rinse the 95% ethanol off with out water not too much. Because the water stop bacteria from decolonization and you want to be able to see the bacteria under the microscope.…
