DNA extraction in Watermelon and Bananas
Abstract During this experiment the researcher investigated the differing amounts of DNA present in bananas and watermelon. So that the researcher could do this, and accurately record the amounts, the researcher liquefied the fruits in a blender, added water and salt to them, and the added laundry detergent before using contact solution as an enzyme. Rubbing alcohol was then poured into the mixture and the DNA was extracted and put into a small container so that it could be weighed. This experiment gave the researcher the knowledge that bananas do in fact have more DNA than watermelon. The results were recorded in a chart and expressed through tables and graphs.
.
Emphasis To create a lab using the scientific method for collection and data, To compare the amounts of DNA in different fruits
Objectives Creating a lab using the scientific method, Discover which fruit has the most DNA
Observations Alcohol aids in DNA extraction. Everything’s DNA is different.
Problem Do Bananas or Watermelon contain larger amounts of DNA?
Hypothesis If there is a difference in the amounts of DNA, then the banana will have a larger quantity, because of its more solid nature.
Null hypothesis If there is a difference in the amounts of DNA, then the watermelon will have a larger quantity, because of the DNA in its juices
Predictions The DNA from the banana will be of a larger quantity because bananas are more solid nature, which gives the DNA more space and a greater of number of places to exist, whereas the watermelons mostly-liquid nature will deny the DNA of some of the space in which it can be.
Independent Variable The fruit
Dependant Variable The amount of DNA extracted
Controlled Variable Room Temperature ( 25˚ C ) Plastic 200 mL containers
Experimental Treatments Jars: Experimental A, Experimental B, experimental C, experimental D,
