needed for this experiment were four medium sized tubes‚ a spectrophotometer‚ a buffer with a pH of 5‚ H2O2‚ Peroxidase‚ and Guaiacol Dye. We as a group had four tubes labeled two‚ three‚ four‚ and five. In the tube labeled two we had a solution of 2.0 mL of H2O2 and 1.0 mL of Guaiacol Dye for a total solution of 3.0 mL. In the tube labeled three we had a solution of 4.0 mL buffer and 1.0 mL Peroxidase for a total of 5.0 mL solution. In the tube labeled four we had a solution of 2.0 mL H2O2 and 1

The investigation on the average mass of DNA with the mass of banana‚ strawberry and kiwi. Purpose: The purpose of this lab is to investigate the comparison between the amount of DNA per gram of fruit that can be extracted from a banana‚ strawberry and kiwi and to determine which one has more DNA. Hypothesis: The banana genome contains 837 MBPs and the strawberry genome contains 206 MBPs and the kiwi genome contains 128 MBPs. This states that there are more base pairs in a banana genome

Melting Point Determination and Thermometer Calibration Lab Background: The melting point of a substance‚ a solid in this case‚ signifies the temperature at which the first crystal starts to melt until the temperature at which the last crystal disappears is reached. That being said‚ melting points are expressed in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

The English word “law” refers to limits upon various forms of behavior. Some laws are descriptive: they simply describe how people‚ or even natural phenomena‚ usually behave. An example is the rather consistent law of gravity; another is the less consistent laws of economics. Other laws are prescriptive - they prescribe how people ought to behave. For example‚ the speed limits imposed upon drivers that prescribe how fast we should drive. They rarely describe how fast we actually do drive‚ of course
