broken and the DNA could not be extracted. When you add the surfactant it softens the cell and the soap dissolves and breaks down the lipids and proteins in the phospholipid bilayer. Much like dish detergent does to greasy dishes. Lipids are insoluble in water‚ the detergent reacts with the cell and causes the molecular contents to fall out much like hydrolysis. Without this you could never complete the extraction. Then you add the baking soda (buffer) to the test tube. Buffer

Large scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes

cleaning product‚ synthetic versions were invented‚ which are now known as detergents. There was also a movement towards using detergents because there was a need for a cleaning agent that did not leave behind a residue as soap did‚ especially on fabric. Upon their appearance‚ detergents became common products for cleaning dishes and clothing. While many people still used regular soap‚ by 1953 most households were using detergents.

Chapter 3: Problem 2: Appalachian Coal Mining believes that it can increase labor productivity and‚ there- fore‚ net revenue by reducing air pollution in its mines. It estimates that the marginalcost function for reducing pollution by installing additional capital equipment is MC 40P where P represents a reduction of one unit of pollution in the mines. It also feels that for every unit of pollution reduction the marginal increase in revenue (MR) isMR 1‚000 10P How much pollution reduction should

Introduction Methionine and cysteine are both sulphur containing amino acids. Most proteins will contain one‚ or both of them at some point in the polypeptide chain. As such‚ many amino acids contain sulphur in some form‚ which is required in small amounts in the mammalian diet. Methionine has a thioether side chain‚ and cysteine’s contains a thiol group. These side chains exist as free thiols inside the cell‚ and are oxidised causing them to pair up and form disulphide bonds in an extracellular

strawberry is because we’d be able to extract more DNA. Ripe strawberries make enzymes which help break down the cell walls making it easier to extract the DNA. We will be using a solution called lysis buffer which is made out of water‚ detergent‚ and salt. The detergent is used to help dissolve the lipid bilayer of the cell membranes. The salt is used to help remove the proteins from the DNA and to keep the proteins in the extract layer so that they aren’t mixed in with the DNA extract. Cold alcohol
