The purpose of this lab is to successfully infiltrate E. coli bacterial cells with a pARA-R plasmid that is antibiotic resistant and has the rfp gene‚ or red fluorescent protein. This can be verified if the E. coli obtains the characteristics of the plasmid when it enters. To start‚ three Petri plates containing agar are needed. On each plate there is a control group and a treatment group; the treatment group being the one with the plasmid. Before the plasmid is put with the E. coli‚ first the bacteria

is a way for men to “be men first‚ and subjects afterward‚” expressing their opinions and acting as a catalyst for change in a free state. Without peaceful resistance‚ there would be little diversity of ideas; the government would control all policy without much regard to minority opinion‚ and scant progress would be made. Peaceful resistance is a means in which citizens are able to influence the laws and encourage progress. From Thoreau’s time to now‚ civil disobedience‚ to put it in Mr. Thoreau’s

Problems with Antibiotic-Resistant Bacteria Antibiotic-Resistance is the ability of bacteria and other microorganisms to resist the effects of the antibiotics they were once sensitive towards (MedicineNet.com‚ 2012). People have been prescribed antibiotics for years to prevent‚ reduce or eliminate infectious diseases. This consumption of these antibiotics has caused our bodies to become resistant towards treatment. Rise of Antibiotic-Resistance When a person goes to the doctor for treatment and are

bacteria. The characteristics of bacteria are altered from an external source to allow them to express a new trait‚ in this case antibiotic resistance. In is experiment foreign DNA is inserted into Escherichia coli in order to alter its phenotype. The goal of the experiment is to transform E. coli with pGLO plasmid‚ which carries a gene for ampicillin resistance‚ and determine the transformation efficiency. The bacteria are transformed by a combination of calcium chloride and heat shock. When the bacteria

parallel circuits. The laws on series and parallel resistors‚ as well as the color code for resistors were observed to calculate the total resistance. The proper connection for ammeter and voltmeter was also conducted and the readings for the voltage and current were obtained. 1. Introduction The objectives of the experiment are to determine the resistance of a resistor based on its color code and to verify the laws on series and parallel resistors‚ as well as the cells. Some practical applications

results of his experiments‚ Georg Ohm was able to define the basic relationship between voltage‚ current‚ and resistance. The equation I = V/R is known as "Ohm’s Law". It states that the amount of steady current through a material is directly proportional to the voltage across the material divided by the electrical resistance of the material. The ohm (R)‚ a unit of electrical resistance‚ is equal to that of a conductor in which a current (I) of one amp is produced by a potential of one volt (V) across

What defines a democracy? Is it the freedom to elect those who will govern us how they see fit? Or is it constant cooperation between the average citizen and the representative to ensure that the country is run in a way that represents our entire society? As our democracy has continued to grow‚ the American public has become less and less confident in their power in our government‚ with many even claiming that their vote does not matter. But this is not what the framers of our country had intended
