    811 words
    Title: Colony Transformation Lab Purpose: To study the behavior of Escherichia coli once it has been introduced to a foreign gene. Hypothesis: If the ampicillin resistant DNA is introduced into the E. coli bacteria, through the uptake of this DNA the bacteria will receive the resistant gene that will permit the bacteria to grow freely in the presence of ampicillin. Experimental Design: By observing the E. coli bacteria one can study how it reacts when a foreign gene such as the ampicillin resist...
  • Bacteria For Drug Resistance

    Since antibiotics, such as penicillin, became widely available in the 1940's, they have been called miracle drugs.

The problem arises when disease causing bacteria interact, and are frequently in contact with the commensal, or harmless bacteria. They serve as reservoirs for ...
  • Bacterial Resistance To Many Antibiotics

    During 1997, an event doctors had been fearing finally occurred. In three geographically separate patients, an often deadly bacterium, Staphylococcus aureus, responded poorly to a once reliable antidote– the antibiotic vancomycin. Fortunately, in those patients, the bacteria remained susceptible to other drugs and was eradicated. But the appearance of S. aureus not readily cleared by vancomycin foreshadows trouble. Worldwide, many strains of S. aureus are already resistant to all antibioti...

    Antibiotic Resistance Darwin's theory Antibiotic Resistance Essay, Research Paper Darwin's theory of evolution can be explained like this; the environment acts as a selective agent, weeding out organisms less able to survive.

The organisms that evolved with beneficial variations are more likely to survive and reproduce, they pass on the favorable genetic material. Over time, the genetic...
