I gave a quiz on chromosomes and the cell cycle to my biology classes today. I could write a book about my emotions before, during, and after quizzes, but tonight I am going to post some interesting responses to one simple quiz question: What is DNA?
We discussed DNA at length in class, and we reviewed it before the quiz. However, judging by some of the answers I got, I'm pretty sure my students pay much more attention to CSI than they do to me.
6. What is DNA?
-- blood. I don't know how to spell it.
-- DNA it's a type of cell in your body for example like blood or saliva that help you find out what type of thing you are.
-- DNA is something that comes out of you like blood, spit, saliva. It can tell people who that person was.
-- someone's blood?
-- sperm/egg
This final response is sort of on the right track, but I find it really funny:
-- DNA is information that tells you about your insides.
I'm still trying to find out what type of thing I am. Maybe I should cut myself and take some DNA out of my insides.

This afternoon, Kim and I had an exchange in the car. It went something like:
ReplyDeleteMeg: "Kim, would you like this piece of gum I just chewed before I throw it away? It has my DNA on it."
Kim: "If I chew it, will I get preggers?"
Meg: "No, you'll just be able to figure out who I am on the inside."
