Plan:
Research for my experiment:
All living organisms have genes which are made up with a biological set of instructions in their Deoxyribonucleic acid (DNA) which determine the characteristics of an organism. No matter who or what you are, each cell will be comprised of DNA inside of it. DNA is responsible for what happens inside of the cell as each cell has an entire copy of the same instructions called genome.
DNA serves many purposes to a scientist, ourselves and other organisms such as plants and animals. Our DNA can help organisms to function properly, and also our DNA can help make new medicines. Scientist are able to genetically modify food to become resistant to insects.
Scientists get the deoxyribonucleic acid out of the cell and study it which is a process called DNA extraction. During the DNA extraction the detergent causes the cell to open up, so the DNA is released into the liquid solution. Salt may be added to allow the DNA to clump together. By adding alcohol the DNA can come out of the solution also known as precipitating.
It is the genes in the DNA, strands on the chromosomes that determines an organism characteristics. The strands are made of sugars and phosphates. The DNA molecules is double strands with base on one strand weakly bonded to its base pair of the other strand. The bonding makes the two strands lock together in a double- helix.
The bases are Adenine, Thymine, Cytosine and Guanine where AT and GC are base pairs. The base order forms a genetic code which determines the types of amino acids used to make up protein molecules. Proteins perform cell functions.

Variables:
My dependent variable is the yield of DNA from the food because my independent variable is the type of food. I will control the amount of other substances such as water, alcohol and dishwashing liquid, which will be precisely measured to make the experiment accurate. My dependent variable will be recorded and measured by using a balance (gram/milligram scale). Since I will be using an equal amount of each type of food I will use a scale to measure out the same quantity for each one. The liquids will be measured with a measuring cup, and measuring spoons for a precise measurements and to keep everything the same.
Risk Assessment:
· Allergies to the food – take precautions of who is allergic so they don’t come into contact with it to avoid any allergic reactions.
· Alcohol spilling – slipping or coming into contact with it near sensitive areas such as eyes or internally consuming it. Wear safety glasses and keep it away from places where it can be possibly knocked over.
· Equipment breaking – injuries or someone getting hurt over broken equipment such as glass being shattered. Check equipment before use in case of already it being damaged and wear enclosed shoes to protect feet.

Timeline for Experiment:
9th April-
Buy all my need materials for experiment such as the fruit and the rubbing alcohol.
10th April-
Put the rubbing alcohol in the freezer over night to make sure its chilled for using it in the experiment.
11 April-
Start my experiment by gathering all the equipment and preparing for my experiment. I will then begin the procedure for conducting my experiment. I will be able to finish my experiment in one day because it does not take long.
12 April-
Conduct my experiment for the second time and improving my results to make the experiment more reliable.
13 April-
Redo my experiment for the third time in order to compare my results and draw a conclusion to my experiment and a summary of my results.
