Restriction Enzymes

Improved Essays
Many organisms have both beneficial and harmful bacteria. These bacteria have special defense mechanisms, virulence, against foreign nucleic acids by using plasmid DNA (Garneau, 2010). pAMP is a special plasmid that bacteria have for ampicillin resistance. With bacteria being able to spread this resistance, other possible harmful bacteria are able to use this to be able to resist ampicillin (Abramovitch, 2006). This creates a harmful or lethal environment for the organism that has the bacteria with the resistance gene (Abramovitch, 2006). In order to find specific sizes of the fragments, scientists use restriction enzymes to put the puzzle together (van der Lelie, 1999). Therefore, the purpose of this experiment is to construct a plasmid map using restriction enzymes. …show more content…
The pAMP sample runs through an agarose gel with the process of electrophoresis. If different restriction enzymes are used to cleave the pAMP, then during electrophoresis, the fragments will migrate down the agarose gel according to the fragment size. Using the results from the electrophoresis and a standard curve, the fragments can be measured according to the migration distance and put together a plasmid map. That being said, scientists are able to use restriction enzymes to figure out how the bacteria obtained the antibiotic virulence and come up with new solutions to halt the spread of enhanced

    Putty was opened on lab computers on the first day of this lab. Next, the group used Putty to input potential restriction enzymes to see where they would cut the DNA, and how long each of these fragments was. The restriction enzymes observed through the program were AseI, BsrGI, ClaI, EcoRV, HindIII, HpaI, NcoI, and PvuII. The lab group then chose to use BsrGI for the experimental restriction enzyme since they believed it would make the mutant DNA linear since it would cut the plasmid once while leaving the wild-type DNA uncut and supercoiled. This would make the wild-type DNA travel faster through the agarose gel in gel electrophoresis.…

    The LB/Amp/Ara (pGLO positive) shown growth colonies on the agar plate. The brilliant green color shown in this plate is called GFP (Green Fluorescent Protein). The Green Fluorescent Protein is expressed only in the presence of Arabinose (Ara). The GFP is expressed after transformation such as a brilliant green color when it was seen in the UV light. The transformation efficiency describes how effective was the transformation of the pGLO added into the E. coli bacteria.…

    The gDNA for the control, A. thaliana was supplied. PCR was then utilized in two rounds with the second using nested PCR. Next, the PCR results were analyzed, and the PCR was purified. Following this step, the PCR product was ligated into a plasmid vector and bacteria was transformed. Next the plasmid had to be isolated from the bacteria and this allowed for sequencing of the DNA (Bio Rad 2017).…

    This restriction enzyme cut the plasmid into two fragments as shown in Figure 1b. The sizes of the fragments on the gel indicate what orientation the plasmids are in. For example, the pKN800A-cut lane had two fragments of 10,500 bp and 1,500 bp while pKN800B-cut lane had fragment sizes of approximately 10,000 bp and 3,500 bp. The intensity of the fragments on the gel has a positive correlation with the size of the plasmid; the band intensity becomes more faint as the fragment sizes decreases. The distance the plasmid DNA migrates is dependent on whether the DNA is completely supercoiled or contains a break in one strand.…

    The first two plates should have had green colony growth and possibly also white colony growth, plate #3 should have had green colonies, plate #4 should have no growth as results showed, plate #5 should have white colonies, and plate #6 should have bacterial lawn as results showed. With better and more accurate results, the transformation efficiencies would have changed as well with higher numbers in ug units.

The ESKAPE relative strain that presented a response to the isolate was B.subtilis. In all cases except for that of LB, the isolate showed antibiotic qualities towards B.subtilis by presenting a zone of clearance on AC and 10% TSA media.…

    In this lab, many materials were used including, EcoRl restriction enzyme, DNA from the crime scene and subjects 1 through 5, centrifuge, water bath, DNA loading dye, Electrophoresis chamber, TAE buffer, and a fast blast stain. The EcoRl restriction enzyme is the enzyme that was used in order to cut the DNA at specific sites into many separate fragments. A centrifuge is a machine that uses a rotating container inside it in order to force all of the liquids to the bottom of the test tubes within the container. A water bath is a heated bath of water which is usually set at a specific temperature that is used to heat up substances. The DNA loading dye was used in order to visually see the DNA against the clear buffer solution and the clear agarose…

    E. faecalis is a gram positive bacterium, which is among the most antibiotic resistant bacteria. Containing many natural antibiotic resistances, it has acquired immunities transferred in r-plasmids among unrestrained bacteria. Since over a quarter of its genome is exogenously attained, this leads to its resistance to the strongest antibiotics or sometimes all antibiotics. This is a large concern in hospital environments and with people with low immune systems since they are more susceptible to infection.…

    Different methods for purification of plasmid exist; during this laboratory experiment specifically kits were used (Qiagen kit). Kits provide the detailed procedures to follow step-by-step and are simple and quicker to perform. This system serves as a fast and simple plasmid purification method for routine molecular biology laboratory applications (Qiagen). This procedure is based on alkaline lysis method of bacterial cells and the by absorption of DNA onto silica in the presence of high salt. Starting with the preparation and clearing of a bacterial lysate, then absorption of DNA, and finally the wash and elution of plasmid DNA are the three basic steps that conform the procedure.…

    Discussion/Conclusion: The majority of the plates had growth in them. The agar plate that had the antibiotics, but not the plasmid had no growth because the bacteria was not introduced to the plasmid that had the antibiotic resistant gene. The LB/amp had growth to it because it was not introduced to any new molecules or chemicals. The po The other plates had growth because they was introduced to the antibiotic resistant gene that made the bacteria able to grow. The positive control of the experiment was the LB plate, because the environment was not changed by any plasmids or antibiotics, which caused this agar plate to serve as the basis of the experiment.…

    coli cells were purified. The plasmid mini-preparation was done using the Qiagen kit to create a solution with purified plasmid DNA. Restriction enzyme digestion reactions used 8 μl of purified plasmid DNA, the EcoRV enzyme, and a cocktail [2]. Then agarose gel electrophoresis, using 1% agarose gel, was done on the digested plasmids [3]. Agarose gel electrophoresis displays the distances that the products had traveled, thus revealing the size of the products.…

    Restriction enzymes bound to then eventually cutted the DNA at a specific nucleotide sequence by cleaving the phosphodiester bonds1. Restriction enzymes bound to specific nucleotide because it is known as sequence specific or as Type II endonucleases1. These enzymes are extracted from numerous bacterial strains in order to determine what bacteria or organism was affecting the DNA sequence. The cleavage of DNA with restriction enzymes lab was conducted to observe the recognition site and cleavage pattern of the organism: Bacillus amyloliquefaciens H (Bam HI) and Escherichia coli RY13 (Eco RI) that affected three different DNA’s.…
