Yeast is a eukaryotic, unicellular organism and belongs to the kingdom of fungi. Saccharomyces cerevisae (or Baker's yeast) is a common form of yeast often used as a model organism due to it's eukaryotic processes, similar to those of animal cells . This species of yeast replicates by budding. Parent cells in cerevisae can be differentiated by scars formed from budding. The other species; Schizosaccharomyces pombe (fission yeast) replicates by elongation then splitting. S. pombe is used in the production of african beer. Breakthroughs in science involve using this model organism to study the checkpoint chemicals used to control the cell cycle which is a major discovery in cancer chemistry.
