9:54Assignment: Which Has More DNA?InstructionsQuestion: Would a kiwifruit and strawberry thatare approximately the same size also haveapproximately the same amount of DNA?Background: You have learned that DNA iscarried on chromosomes. All mammals arediploid; however, not all plants are diploid. Thecommon strawberry is octoploid (8n) and thecultivated kiwi is hexaploid (6n). Research thetotal number of chromosomes in the cells of eachof these fruits and think about how this mightcorrespond to the amount of DNA in these fruits'cell nuclei.Hypothesis: Hypothesize whether you would beable to detect a difference in DNA quantity fromsimilarly sized strawberries and kiwis. Which fruitdo you think would yield more DNA?Test your hypothesis. Perform the DNAextraction experiment.Record your observations: Because you are notquantitatively measuring DNA volume, you canrecord for each trial whether the two fruitsproduced the same or different amounts of DNAas observed by eye. If one or the other fruitproduced noticeably more DNA, record this aswell. Determine whether your observations areconsistent with several pieces of each fruit.Analyze your data: Did you notice an obviousdifference in the amount of DNA produced byeach fruit? Were your results reproducible?Draw a conclusion: Given what you know aboutthe number of chromosomes in each fruit, can 9:54 1Assignment: Which Has More DNA?correspond to the amount of DNA in these fruits'cell nuclei.Hypothesis: Hypothesize whether you would beable to detect a difference in DNA quantity fromsimilarly sized strawberries and kiwis.

Can youidentify any drawbacks to this procedure? If youhad access to a laboratory, how could youstandardize your comparison and make it morequantitative?To complete this assessment, address all of thepoints above in a lab write up. Be sure to includeimages of your experiment in progress. See theexamples contained here.
