Purpose In this lab‚ we used PCR and gel electrophoresis to identify genetically modified food. Introduction A genetically modified organism is an organism whose DNA or genetic makeup has been modified to code for certain desirable traits("Genetically Modified Foods"). Common genetically modified plants include corn and soy‚ and common genetically modified animals are fish. Many genetically modified plants are coded to resist bugs‚ grow faster‚ and produce bigger fruit‚ while most GMO animals

Switzerland. They found a material that reached superconductivity at around 35 degrees Kelvin or 238 degrees Celsius. In the next year‚ a team of Chinese-American physicists declared that they had found a material that reached superconductivity at 92 degrees Kelvin. This was a big improvement. 92 degrees Kelvin is not a very high temperature‚ in fact‚ it is the equivalent of 181 degrees Celsius. Locating superconducting material above 77 degree Kelvin is a good thing because it means that the material

provides a positive result for: sulfur reduction‚urease production‚ tryptophan deaminase production‚ and indole production. It’s not limited to any specific temperature range‚ but good growth occurs at 20 to 30 degrees Celsius‚ while growth is poor at 37 degrees Celsius. P.vulgaris has two interesting features. The cells are highly motile and swarm across the surface of the agar plates‚ forming a very thin film of bacteria. When the cells stop and undergo a cycle of growth and division

Abstract In the following project we are discussing about distillation. The operation of the distillation is employed for the purification of liquids from non-volatile impurities. The liquid is heated to the vapor phase and then is collected and recondensed to give back the pure liquid .The non-volatile impurities are left behind in the flask. Here our main focus will be at the fractional distillation. It is the process in which we separate the different components of a mixture on the basis of the

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

I. Aim The aim of the three experiments is actually to investigate the effects of different factors such as temperature‚ pH‚ and concentration of substrate‚ on the activity of the enzymes. By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase

and becomes ill or dies. This whole experiment is based on purifying and then finding the melting point of the unknown compound. The theory is that if a substance is pure‚ it will have a very specific melting point‚ within one or two degrees Celsius. This is in opposition to a mixed‚ or contaminated substance‚ which will have a broad melting range. Therefore‚ when we mix our unknown with samples of phenacetin and acetanilide‚ whichever mixture has a more accurate melting point will tell us what

Results: For the room temperature experiment the water had a starting temperature of 24 degrees Celsius and a pH of 6. The vinegar had a starting pH of 1 and a temperature of 24 degrees Celsius. During the time the whole and crushed chalk were in the water nothing happened besides the water turning a little bit cloudy. While in the vinegar the whole chalk broke down‚ turned the water a tint of
