Edible DNA
Make a DNA model you can eat!
Genomics is one of the most rapidly advancing areas of science with research providing solutions to a vast number of global challenges.
Genome BC believes in supporting education by providing tools to teach students about this complex topic in new and interesting ways.
Geneskool provides a variety of resources and programs that make learning about genomics fun for students in grades 9 through 12.

Things you need
Licorice is used as the backbone
Toothpicks are used as the bonds
Four different coloured mini-marshmallows to use as your four nucleotide bases. (Jelly beans or fruit can also be used.)
WHY MUST A & T AND G & C ALWAYS GO TOGETHER?
For attraction to occur between any two molecules, their atoms must line up just right. Adenine pairs with Thymine because there are 2 Hydrogen molecules in just the right place to form a non-covalent bond. With Guanine and Cytosine, there are 3 Hydrogens. It is these bonds (and their arrangement) that give DNA its unique ability to unzip right down the middle, which is crucial for DNA replication and protein synthesis.

Enjoy!
CREATE ONE DNA STRANDCreate one DNA strand by attaching the marshmallow with a toothpick to one licorice piece.
STEP 1
STEP 2ADD THE MATCHING BASE PAIRSPartner up the matching base pairs. A with T and G with C. Attach the other piece of licoriceso your model looks like a ladder.
STEP 3CAREFULLY TWIST YOUR DNA MODELYour model should look like a double helix.
Before you startAssign each of the 4 different colours of marshmallow to represent one DNA nucleotide: A, G, C or T
