Chewy DNA

This week we did this lab, Have Your DNA and Eat it Too, from the Utah site. We used cinnamon Twizzlers and Dots. I can't recommend the Dots; the indistinct color differences and number of each color in the box was problematic. I wanted to show how DNA can be replicated with minimal mistakes but even in 3 boxes of Dots I didn't have enough green dots and yet had many, many red dots.Candy and science, a good combo. I need to think of some way to use chocolate, though. PRM

What an excellent way to model DNA, and to make it very memorable. Watson and Crick would be proud :-)

I'm thinking that if Watson and Crick had only had some toothpicks, Dots and Twizzlers they could have figured it all out so much quicker. Or Rosemary Franklin could have shown them.
