Quantification of DNA Using Agarose Gels
Directions: Please answer the following questions in complete sentences.
What problems might arise if the agarose wasn't dissolved/melted
completely or if there were air bubbles in the gel?
Why did your DNA samples need to be mixed with a loading dye
prior to loading the samples into the gel? Give 2
reasons.
What causes the DNA to travel through the gel?
Draw a sketch of what your gel would have looked like (after 5
minutes) if you reversed the positive and negative leads and placed
the positive lead closest to the wells. Label the
positive and negative leads, the wells, and the DNA.
Why do smaller DNA fragments travel further down the gel?

Read the two articles (links below) and then address the following
questions in your post.
Would you be interested in having such a genetic test done? Why or why not? If you have had a consumer DNA test done and would like to share your experiences, you are welcome to do so.
Would you want to know if you were destined to contract an incurable degenerative disease such as Huntington's disease or Alzheimer's later in life? Would the results of such a test cause you to alter your lifestyle?
What concerns (with regard to ethics, privacy, etc.) might arise with the widespread use of such tests?

Your Crop Domestication - Tea
Your goal is to explain the history of your plant's domestication by humans (specific questions to address below). Using your book and any other reputable sources (Links to an external site.)Links to an external site.,
Questions to Address:
1. Where did the wild type ancestor of your crop originate?
2. Where did crop domestication first take place? Note: This may or may not be the same place as #1.
3. How do the wild type ancestor plant and the modern plant differ from one another? Specific trait(s)!
4. How, where, and when did the domesticated plant travel from its original domestication place?
