encoded by EZH2‚ the EZH2 gene encodes part of the Polycomb group which make protein complexes that help to maintain genes transcriptional repressive state over successive cell generations. http://www.ncbi.nlm.nih.gov/gene/2146 Throughout this lab report template DNA that contains the gene EZH2 was provided‚ this will be amplified by a PCR and cloned into a vector. This Polycomb group proteins help maintain the cell identity during progress through chromatin

how a specific pH level would impact tyrosinase activity. First we added 4.0 mL of pH in each corresponding test tube and then added 0.5 mL of substrate (catechol) into each test tube. In the instructions it says to apply your 0.5 mL of tyrosinase (potato extract) as well but you have to blank the spectrophotometer before. The results from this experiment confirms that our hypothesis of a neutral pH displaying a stronger impact on tyrosinase is true. According to our results the pH levels at a more

reaction. Therefore‚ it will be presumed that the result of this experiment by isolating the polyphenol oxidase within the potato extract through the oxidation of 5mM dopa solution with highly concentrated enzymatic preparation of polyphenol oxidase with a buffer as the diluent will indicate a rapid increase in the rate of the reaction as well as the amount of activity present in the potato extract. Proposing that Vmax is proportional to enzyme concentration‚ a linear relationship should be present and enzymatic

chelators‚ ethylene diamine tetraacetic acid and phenylthiourea to test which would stop the effects of catechol oxidase on potato cells by testing the change in absorbency over time. Our data supported our hypothesis that EDTA would have a greater change in absorbency over time than PTU. Environmental Parameters of Enzyme Activity Introduction In this experiment‚ we used potato cells (CO) to act as

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

demonstrate the process of osmosis using potatoes‚ and to determine the concentration of the cytoplasm of the potato. To demonstrate this‚ we had 6 test tubes and poured in different sucrose solutions of the following concentrations: 0.0M‚ 0.1M‚ 0.2M‚ 0.5M‚ and 1.0M. Once added in with all the sucrose solutions‚ we added in the 6 cylindrical potatoes of equal diameter and length. Before and after putting it in the potatoes‚ we had to weigh the initial and the final mass of each potato. After you have left
