In this activity, learners apply the concepts of pixilation and pointillism to the world of biomedical science. They learn how DNA microarrays and supercomputers help in disease detection by organizing large amounts of data points from our human genome. Learners discover that categories of disease can be sorted based on color-coded expression level patterns on microarrays. In particular, learners evaluate what genes are turned on and off in a patient suffering from a particular disease. Learners use Cheerios stacks to create microarrays and simulate the gene matching (hybridization) process that happens in cells.
