used worldwide in biotechnology laboratories. A "Filtrate" is made of onions treated with salt‚ distilled water and detergent(SDS). An onion is used because it has a low starch content which allows the DNA to be seen more clearly. The salt shields the negative phosphate end of DNA which allows these ends to come closer so they can precipitate out of a cold alcohol solution. The detergent causes the cell membrane to breakdown by

and hormones. DNA can be extracted from many types of cells. The first step is to lyse or break open the cell. This can be done by grinding a piece of tissue in a blender. After the cells have broken open‚ a salt solution such as NaCl and a detergent solution containing the compound SDS (sodiumdodecyl sulfate) is added. These solutions break down and emulsify the fat & proteins that make up a cell membrane. Finally‚ ethanol is added because DNA is soluble in water. The alcohol causes DNA to precipitate

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

In this‚ the sufferings from buying commercial dishwashing liquid that contributes to our daily cost and the suffering that we face in using detergent bar in plates will be lessen or will be decrease. Instead of using harmful chemicals in manufacturing dishwashing liquid‚ we replaced it with Banana peelings as an effective cleaning agent. Through this we can help to ease the case of water pollutions

In this lab‚ we added a buffer solution composed of salt‚ clear dish detergent‚ and deionized water for procedure 1( the strawberry part). For procedure 2( our cheek cells)‚ we used the same buffer solution but added red food coloring so we can distinguish the DNA from the rest of the cellular components because it was all a white mixture
