In today’s world Biology plays an important role. It provides us with means to staying alive as well as the understanding of how we are alive and where we came from. Our origins have been a question that’s eluded our knowledge since our conception. Many a scientists have embarked on the quest to understand our origin. Over the centuries it seems as though we are getting closer to the answer. A description of the process of the theory of Evolution […]
Introduction The importance of being able to identify bacterial unknowns allows us to determine potential pathogenic microorganisms that can be harmful to humans. The identification of bacterial unknowns provides information to medical professionals to diagnose and properly treat patients with therapeutic strategies such as prescribing antibiotics to kill specific pathogenic microorganisms. Possible methods to identify bacterial unknowns include basic differential staining and biochemical tests. Gram staining allows identification of the morphology and cell wall structure of a bacterial unknown, which […]
By: Jacob Lucht Purpose: The purpose of this experiment was to determine the type or types of bacteria living in each person’s skin by taking a sample from the nose and plating it on a selective, differential media to culture it and then using polymerase chain reactions to amplify the DNA of the bacteria and gel electrophoresis to determine which type of bacteria was present. Theory: The human body has a large number of bacterial species living on and […]
Summary Report II This report contains information from labs three and four. These labs were the continuation of previous weeks and in process of obtaining the same overall goal. The semester long lab is broken down into important milestones that must be accomplished to move to the next step. The milestones are explained in the next paragraph. The semester long project as previously stated in the prior summary may have been unclear. The purpose of this semester long lab is […]
Area I conducted my study in and around Mere Knolls Cemetery and Seaburn Dene. I chose this piece of land as my area of study because the effects of humanity and nature are both prominent in this area, and so it would provide good points of discussion in this ecological study. The area I studied is highlighted by the red outline. As you can see, there is a variety of different types of land within and around the cemetery, such […]
Transfer of Escherichia Coli By: Amudha Venugopalan, Sarah Councilor, and David Roehrich Introduction: Escherichia coli are prokaryotic bacteria that can be transformed by lateral gene transfer. E. coli are transformed by direct transfer which means the bacterial cell directly uptakes the DNA of the plasmid introduced to it (Wimpee et al. 2013). A plasmid is a circular small piece of self-replicating DNA, plasmids carry fewer genes therefore DNA can be passed between species of bacteria (Wimpee et al. 2013). The […]
