    Restriction Endonuclease Digestion of DNA from E. coli cells and Analysis by Agarose Gel Electrophoresis Introduction The main goals of this experiment are testing an alternative procedure called “boiling lysis”‚ evaluating the quality of the purified plasmid for restriction digests‚ and identifying the mislabeled plasmid. The plasmid DNA from a carrier E. coli strain was purified by the boiling lysis. In the boiling lysis method‚ the bacterial cells were given momentary heat treatment

    Gel electrophoresis is a routine laboratory procedure in biochemical studies that takes advantage of a protein’s amphoteric nature to determine its molecular weight and charge by running the sample through a gel matrix under the influence of an electrically charged field. A popular example of gel electrophoresis is Sodium dodecyl sulfate-polyacrylamide electrophoresis or SDS- PAGE which has been used in this experiment to supposedly determine albumin and casein’s molecular weights respectively. The

    They also used flow cytometry to help them to identify and sort through the cells and their DNA by staining them with a fluorescent dye and detecting the fluorescence through a illumination microscope. This helped them to calculate the number of replication forks per cell‚ along with the cells age and size at initiation. The researcher did an excellent job describing each media and staining technique that they used during their experiments. For example‚ they explained exactly how much nutrient
