Glowing bacteria lab essay example

After the solution finished draining into collection tube 3, it glowed a bright green while the previous collection tubes had completely lost their glow.

Some bacteria contain inclusion of iron granules called magnetosomes which permit them to orient their movement in response to magnetic fields.

Glowing Transformations Essay Sample

Although they are not very complex morphologically, the tiny bacteria nevertheless have highly complex physiological, biochemical, cytological, and genetically characteristics making them a valuable tool for understanding the various intricacies of life.

Then, this gene to be transferred is forged into the plasmid in this lab we used previously made plasmids called pGLO, containing a bioluminescent gene and a gene for ampicillin resistance. If one projects a small spot of light onto a thick suspension of Chromatium on a slide previously kept in the dark, the organisms can be seen to collect in the illuminated area.

Mycobacterium are rod-shaped, pleomorphic, and may undergo branching or filamentous growth. During purification, the final glow in collection tube 3 with no other tubes glowing showed that the GFP gene was isolated.

More essays like this: My prediction for this future lab would be both antibiotics would be able to treat several other bacterial infections. From this lab, we can conclude that bacteria—through the process of transformation—are able to take up foreign DNA such as in the form of a pGLO plasmid and express it in phenotypic characteristics such as glowing.

Finally, each transformation solution was prepared. More specifically, a previously prepared pGLO plasmid—which consisted of the gene to be cloned—was used to transform non-pathogenic bacteria.

Again, the similarities are the determination of cell transformation. Our data fully supported our hypothesis. Data, Observations and Calculations: Behavioural Responses of Bacteria: Using a sterilized inoculating loop, obtain a loopful of bacteria from the plasmid DNA stock tube.

Cell wall appears thick and homogenous. The following day, the agar plates were removed from the incubator and observed. Other functions are also attributed to teichoic acid such as binding metals and acting as receptor sites for some viruses.

The cocci bacteria [Fig. Page 1 of 3 Bio 11H lab Introduction: There are so many ways that transformation can help the human race find cures for diseases, viruses, and problems that arise with said cures.

Pglo Transformation Essay

Mycobacterium possesses a distinctive straining property called acid-fastness which is due to the presence of unique lipid component called mycotic acids only found in the genus Mycobacterium.

Bacteria show considerable variation in characters almost themselves, they possess many characters common to all. After examining collection tube 3 under the ultraviolet light and taking notes, the collection tubes were all sealed with Seran Wrap and placed in the refrigerator until the next lab period.

This process is quite different from transfer of genes from parents to offspring vertical gene transfer, in sexual reproduction in eukaryotes. In addition to low water content, the pH of the core cytoplasm is about one unit lower than that of the vegetative cell and contains high levels of core-specific proteins, namely, small acid- soluble spore proteins SASPs.

The flexion is caused by contraction of fibrils called crista. Obviously the plasmid did non transform at a really high rate into the bacterium because of little sum of settlements on the home base. Lastly, we put our plates in an incubator so bacteria could grow, and observed them the next day under UV light.

None of the results came out the way they were intentionally supposed to and the entire experiment just did not work as expected. Peptidoglycan, the main constituent or back-bone of bacterial cell wall, consists of two parts: Get Full Essay Get access to this section to get all help you need with your essay and educational issues.

BMC Cancer It was shown in the results that when the gene for tumor suppression is inactivated, this is when oncogenes begin to transform normal human genes, and sometimes cause cancer. However, the diaminopimelic acid DAP does not occur in the peptidoglycan of all bacteria; only all gram-negative bacteria and some gram-positive bacteria possess it.Transformation Lab Report Introduction Transformation is the transfers of virulence from one cell to another, through the transferring of genetic material.

It was originally postulated in through the works of Federick Griffith, a British microbiologist. Griffith observed that the mutant form, non-virulent form, of the bacteria Streptococcus Pnumoniae could be transformed into the normal. From this lab, we can conclude that bacteria–through the process of transformation–are able to take up foreign DNA (such as in the form of a pGLO plasmid) and express it.

Pglo Transformation Essay. Connor Lauffenburger 3/17/13 pGlo Transformation Lab Report I Introduction The purpose of this experiment was to show the genetic transformation of E - Pglo Transformation Essay introduction.

coli bacteria with a plasmid that codes for Green Fluorescent Protein (GFP) and contains a gene regulatory system that confers ampicillin resistance. 1 Glowing Bacteria! Purpose: To use your knowledge about genetic transformation to successfully transform E.

coli cells to produce green fluorescent protein. Background: The gene encoding green fluorescent. AP Bio pGLO Transformation Formal Lab Report Essay Sample.

Abstract: The topic of this research involved the occurrence of genetic transformation in bacteria (E. Coli). When we rehydrate the plasmids, the gene necessary to produce glowing bacteria, along with several genes that are part of the control for the experiment will be contained in a neat package that the bacteria will take up on its own.
