Biology Experiments 2: Supplementary Experiments

The experiments on this page are a continuation of the experiments on Biology Experiments 1. These experiments are grouped under the heading 'Supplementary' because they are either (i) extensions of previous experiments, (ii) involve more expensive reagents, (iii) need specially prepared apparatus, (iv) are more complicated than those in the previous list, or (v) more suited to advanced students. The experiments are offered in Word format. If you do not have Microsoft Word installed you can download Word Viewer free here.
