Summer STEM – DIY DNA
DIY DNA
Week 5 of Summer STEM from Your LibrarySolve who broke into the Bears' house and ate their porridge by making this tasty DNA strand. There are four types of chemical bases in DNA. They always form the same pairs. Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G) Write in a jellybean color for each chemical base to make sure you pair them properly!
A: ___________________
T: ___________________
G: ___________________
C: ___________________
Put a jellybean on one end of a toothpick.
Match your chemical base pairs by adding the second jellybean. Remember that A always pairs with T, and C always pairs with G!
Push the tip of each toothpick into a licorice twist on either end. Give it a twist to see the shape of a double helix.
