The independent variable in this experiment is the strawberry mixture while the dependent variable is the amount of DNA extracted. The cold ethanol was added to the soap and salt mixture to precipitate the DNA from the other cell material to form the final product.
The large solids were then separated by filtration, and the resulting solution was collected in a test tube. The same applies to DNA in this experiment. The Sodium and Chloride ions are more charged and much more polar than the proteins and carbohydrates—that is why the polar molecules displaced them out of the solution.
They are both proteases, meaning they break apart proteins. For example, plant seeds yield a lot of DNA because they have very little water in the cell cytoplasm. So the DNA is relatively concentrated. When soap comes close to grease, their similar structures cause them to combine, forming a greasy soapy ball.
The detergent degrades the phospholipid bilayer of the cell and nuclear membranes after the strawberry is crushed. Allow more time for each step to complete. Discussion Questions To extract DNA from cells, what must you isolate it from in the case of a plant such as strawberry?
The section of DNA containing this particular gene can be inserted into a different organism so that the altered organism now has a specific trait that it did not previously carry.
Both soap and grease molecules organize themselves in bubbles spheres with their heads outside to face the water and their tails inside to hide from the water. I chose strawberries lab.
