(Remove the skin of the bananas and kiwi, we just want the insides!) Altering Animals. DNA contains the instructions required to build each living thing. The nanodrop system revealed that at an absorption of 260 wavelengths, the DNA measured 7.49 using a 374.66 ng/ul sample. Even though the procedures vary considerably, they involve three main steps: lysis of cell wall, cell membrane and nuclear membrane, isolation of DNA from other cell inclusions, and purification of the extracted DNA. All of these instructions fit within tiny packages within our tiny cells, so that is all way too tiny for anyone to ever really see or touch, right? Place the banana onto a plate.

All of the above steps are completed in the same manner for the banana DNA extraction except for the adding of water during the smashing of the fruit. This DNA extraction is simple and works every time but the DNA is not pure. The actual DNA structure is seen as a double helix in which two strands are wound around each other. The four nitrogenous are A(adenine), G(guanine), T(thymine) and C(cytosine). Add the dishwashing soap into the bag and gentlymix, trying not to make it foam up. In 1944, a group of scientists led by Canadian biologist Oswald Avery performed an experiment that would determine which molecule in a heat-killed bacterium was most important for transformation to occur. Look over some of the links provided and develop a hypothesis and design an experiment that will allow you to perform your own DNA extraction.
