Year 12 Biology HL students were asked to create DNA models that illustrated their knowledge of the DNA structure. Here is the criteria that was given to the class:
Construct a model of the DNA molecule. Your final model must meet the following criteria:
1. It must be self-supporting, stand at least 30 cm high and have a diameter of at least 12 cm
2. It must clearly model the double helix structure of the DNA molecule
3. Each of the major components of the molecule (bases, sugar, phosphate) must be clearly recognizable using labeling, colour coding, shape, size, material or any combination of the above. Purines must be distinguished from pyrimidines.
4. 3’ and 5’ ends are shown
5. A minimum of six base pairs must be represented
6. Correct number of hydrogen bonds between base pairs must be demonstrated in the model
The models were a great success!
