Students used candy to model the structure of DNA. The students were provided a base sequence of one strand. They were expected to build that strand and then likewise the complimentary strand.
Each nucleotide consists of a deoxyribose (red licorice), a phosphate (marshmallow), and a nitrogenous base (candy heart). It is important that the deoxyribose and phosphates make up the back bone and that the bases are bound to the deoxyribose.
The candy heart bases are as follows:
Once a single strand was created, the complimentary strand was created including the backbone (deoxyribose & phosphate) as well as the complimentary bases (A to T and G to C).
The original strand was glued in place for a future activity. Icing was used as glue.

The candy heart bases are as follows:
- Thymine - Yellow
- Adenine - Pink
- Guanine - Orange
- Cytosine - Purple
