A friend and I are doing a project for our Honors Bio class.  Using a low-
tech prep, we extracted DNA from 10 different fruits and vegetables.  When 
we weighed the amounts of DNA, the results were very different, and when 
we did gel electrophoresis, there was no pattern between the ones that 
yielded the most and the ones that had the best DNA.  We were wondering 
why this may be.
