Brandon Schmetterer 3-13-15 Biology labs DNA Extraction Lab DNA is extracted from humans for genetic testing‚ for body identification‚ and for analysis of forensic evidence. The first step of DNA extraction is to take cheek cells from the test subject. Next‚ the cells must be burst open in order to release DNA. Third‚ DNA is separated from protein and debris. Lastly‚ the DNA must be isolated. A buccal swab is necessary in order to collect the cheek cells .The micropipettes are used to add lysis

DNA Extraction Lab Purpose: To compare the amount of DNA extracted from two different species‚ despite using the same method. Hypothesis: I predict that the liver will produce a higher quantity of DNA than the strawberry. This is because I believe that animals have a higher DNA yield because our structure is more complex than a plant’s structure. Materials: -Sample of Strawberries -Zip lock bag -DNA extraction buffer -Cold ethanol -Glass rod -Double ply cheese cloth -Two test tubes

The Effect of pH on the Rate of Enzyme Catalysis of Catalase Objectives: The objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme. More specifically‚ the objective was to perform an experiment in order to test the effect of pH on the function of the enzyme catalase. Introduction: Enzymes are proteins that act as catalysts for reactions. This simply means that enzymes lower the activation energy required

classroom assessment to support learning. However‚ the ‘accountability’ juggernaut was not for turning‚ even though the Blair dynasty’s clarion call of “Education! Education! Education!” had not yet begun to ring hollow. It was the day we decided to up the ante and make it our target to resurrect assessment by teachers‚ not to abandon testing‚ but to refocus assessment activities where they should be‚ on pupil learning. The King’s College pair had been long-term advocates of formative assessment

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of

“too acidic to justify the worth of drinking every morning for the miniscule amounts of vitamin C it contains” (Dr. Kenny and Henderson). It has been found that orange juice‚ while it does contain vitamin C‚ does not contain enough vitamin C to live up to the “super food” standard that was set for it in the past. Instead of assisting one’s immune system‚ it has now been discovered that due to the naturally high acidity of orange juice‚ they actually are detrimental to ones health. Drinking orange
