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. 400–575 West 8th Avenue Vancouver, BC V5Z 0C4 Visit genomebc.ca /geneskool supported by 0103.002.003 08/18 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.
