Discussion The purpose of this experiment was to be able to better understand the properties associated with DNA in live organisms and to find out how to isolate and quantify DNA in plant materials using Dische diphenylamine. This particular experiment could be very useful to scientists as a similar procedure could help identify genetic diseases and could also aid in finding cures for those genetic diseases. Based on assumption our hypothesis was formed and it was believed that the banana would yield the most DNA after undergoing our test. We came to this assumption from the idea that the banana was denser than the other samples, and would …show more content…
In the very first steps of the procedure we were instructed to mash the sample into small pieces and there was a huge difference in the appearance of the banana and the other fruits. The banana was not only harder to mash but had a thicker consistency than the raspberry, blueberry and blackberry. After adding the Dische diphenylamine, the color could be recorded and we were also able to record the Abs600. From this point we were able to calculate the concentration, the total DNA yield and the percent DNA. From our DNA yield data our hypothesis could be proven incorrect based upon the fact that the banana actually had the smallest amount of DNA with .138% and the raspberry had the highest yield with 1.93%. Our graph clearly shows these yields and also helps prove our hypothesis to be
