Many laboratories find it useful to perform parallel experiments in two or more model systems to understand different aspects of a biochemical process. X. tropicalis is a small ~5 cm, flattened-body frog with small eyes commonly found in subtropical lowland forests and rivers throughout West Africa. I identify the major reasons for this and discuss limitations of this organism for future progress in research on aging. Clonal Analysis. However, different human tissues, while inheriting a similar genetic code, exhibit distinct anatomical and physiological properties. The most popular model organisms in biological and biomedical research are the fruit fly Drosophila melanogaster, the zebrafish and the nematode C. elegans. 0000000016 00000 n In biology, model organisms are used to study processes that cannot be easily measured in humans.
