Purpose The purpose of this experiment is to extract DNA from a banana breaking down the walls of the cells, along with the plasma membranes and nuclear membranes. 3. Hypothesis My hypothesis is that adding dish soap, the membranes around the cells and the nuclei will break down, leaving the DNA alone (since dish soap breaks apart lipids and ...
If you took all of the DNA out of some middle-sized organism (or part of an organism, like a piece of fruit), you could see and even touch DNA. We will use common household products to break apart the cells in a banana and extract out the DNA. While you may know of the double-helix structure of DNA, you can't see that structure with the naked eye.
Hypothesis. Example 1: Because some fruits are polyploids, using different kinds of fruit should result in the extraction of different amounts of DNA. Example 2: The type of fruit used will affect the amount of DNA extracted because some fruits have different numbers of chromosomes.
All living things, bananas and people included, pass on information from one generation to the next using the same basic material, DNA. Within every living organism, most cells contain a complete set of DNA instructions. The information in DNA tells our bodies how to develop, grow, and work.
12 maj 2011 · Just like us, banana plants have genes and DNA in their cells, and just like us, their DNA determines their traits. Using only our eyes, we couldn't see a single cell or the DNA inside of...
Experiment to purify DNA from fruit. Step 1: Mash up the fruit of your choice in a bowl. Bananas, kiwis and strawberries all work well. (Remove the skin of the bananas and kiwi, we just want the insides!) Step 2: In a separate bowl, mix the washing up liquid, salt and tap water. Stir gently trying to avoid making too many bubbles in the mixture.
