EXTRACTION OF DNA FROM ONIONS ABSTRACT The purpose of the experiment was to experience firsthand the isolation of DNA form a plant tissue without destroying its structure and sequence. A white onion was used for the experiment. After several processes‚ DNA isolate was the visible result. Different chemical tests were performed on the DNA isolate‚ namely: Dische Test‚ Murexide Test‚ Wheeler-Johnson test and Test for Phosphate. Visible results were then noted. INTRODUCTION DNA (deoxyribonucleic

Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If the

I do not agree that companies should stop investing in “pushing promotions” and put their money into attracting consumers to the company with so called “pulling promotions”. They each serve their purpose in the very diverse market of consumers. “Pushing promotions” are more useful at the start of a

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

I love seeing children have "light bulb" moments. It’s moments like those that let you know you have chosen the correct profession. I also chose teaching as my profession because when I was in elementary school I did not have good teachers to look up at. I struggled a lot in elementary school and my teachers just saw me as the problem child they did not have time to help. They made me feel horrible because I didn’t know the answer to a question they asked‚ or I needed help with something they thought

Endurance INTRODUCTION: The Frog that Never Give Up A group of frogs were traveling through the woods and two of them fell into a deep pit. All the other frogs gathered around the pit. When they saw how deep the pit was‚ they told the two frogs that they were as good as dead. The two frogs ignored the comments and tried to jump out of the pit with all of their might. The other frogs kept telling them to stop‚ that their struggle was worthless. Finally‚ one of the frogs‚ tired and discouraged

5/2/2006 Aim: Does the resistance of a filament bulb change as the bulb gets brighter? Hypothesis: I believe that a filament bulb will have an increasing resistance depending upon the current passing through it. Equipment: *Power Supply *Wires *Ammeter *Voltmeter *Filament bulb with holder *Alligator clips *Switch Method: 1.Set up the circuit according to the schematic diagram 2.Use the alligator clips to connect the filament bulb to the voltmeter 3.Connect the power supply to the electricity

Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement
