Document Summary
Because of the large number of organisms on earth, it is not possible to study more than a few of them in detail. By studying a few representative organisms, what we learn can be extended to many other organisms. Use of model organisms is particularly important in research on human disease and development because ethical constraints limit the use of human subjects, and the long development and generation time in humans slows the pace of research. In a recent political campaign, a candidate criticized public funding for research involving model organisms: Even saccharomyces cerevisiae (baker"s yeast), a very simple eukaryote, has a cell cycle that is extremely similar to that of humans and is frequently studied to understand the process. A good model organism has the following features: Less complicated than other species sharing its. Fast life cycle and large number of offspring features. Saccharomyces cerevisiae (baker"s yeast) eukaryotic cellular processes, genetic manipulation.
