Science Year 2 Date: 7th- 14th of February 2014. Title: Ligation of Lambda DNA pre-digested with EcoRI and HinDIII. Restriction of Lambda DNA with restriction enzymes. Aim: The objectives of this experiment are: Become more familiar with using micropipettes. Use restriction enzymes to cut DNA at specific sites. Use Ligase to rejoin some of the cut/separated DNA fragments. Learn to separate DNA using electrophoresis. Introduction: Restriction enzymes are proteins

Lab 2 – Water Quality and Contamination Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell‚ Color‚ Etc.) Beaker Observations 1 The water is clear with no distinct smell. 2 The vegetable oil does not mix with the water. Oil on top‚ separated from the water. Oil has a slight yellow look to it. No odor. 3 Vinegar mixes with the water and retains clarity. Has a slight smell of vinegar to it. 4 Laundry detergent changes the water’s clarity to a blue-green color. It has

Factors Affecting Enzymes The activity of an Enzyme is affected by its environmental conditions. Changing these alter the rate of reaction caused by the enzyme. In nature‚ organisms adjust the conditions of their enzymes to produce an Optimum rate of reaction‚ where necessary‚ or they may have enzymes which adapted to function well in extreme conditions where they live.Increasing temperature increases the Kinetic Energy. In a fluid‚ this means that there are more random collisions between molecules

Use of Enzymes in Food Industry - Food industry utilizes a variety of enzymes for processing of various foods‚ e.g.‚ production of various types of syrups from starch or sucrose (a- and β- amylases‚ glucamylase‚ pullulanase‚ invertase‚ and glucose isomerase)‚ meat/protein processing using proteases‚ removal of glucose and or molecular oxygen (O2) using glucose oxidase and catalase‚ use of lactase in dairy industry and use of enzymes in fruit juice and brewing industries. Glucose oxides are obtained

15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site of enzyme to transfer in to one or
