2. A nucleic acid that contains genetic
information.
Double helix shape
Composed of nitrogenous bases (adenine,
cytosine, guanine and thymine), a five-carbon
sugar (deoxyribose), and a phosphate
molecule.
5. Aim: To create a model of DNA using lollies.
Equipment:
- red licorice sticks (phosphate)
- black licorice sticks (sugar)
- gummy bears (4 different colours) (bases)
- toothpicks (bonds)
6. Method: Design your own method
Results: Draw your DNA model with a key
Editor's Notes
Call volunteers to label the 4 nitrogenous bases, the 5-carbon sugar and the phosphate.
