Saccharomyces cerevisiae is a species of budding yeast. It is perhaps the most relevant yeast for mankind, both for its use since ancient times in baking and brewing, and for being one of the most intensively studied eukaryotic model organisms in molecular and cell biology, much like Escherichia coli as the model prokaryote. It is the microorganism behind the most common type of fermentation. Saccharomyces cerevisiae cells are round to ovoid, 5-10 Micrometres in diameter. It reproduces by a division process known as budding.

It is useful in studying the cell cycle because it is easy to culture but as a eukaryote, it shares the complex internal cell structure of plants and animals. S. cerevisiae was the first eukaryotic genome that was completely sequenced. The yeast genome database [1] is highly annotated and remains a very important tool for developing basic knowledge about the function and organization of eukaryotic cell genetics and physiology. Another important S. cerevisiae database is maintained by the Munich Information Center for Protein Sequences [2]. Saccharomyces cerevisiae was the first eukaryote to have its genome sequenced (published in 1996). The genome is composed of about 13,000,000 base pairs and 6,275 genes. It is estimated that yeast shares about 23% of its genome with humans. The cell cycle, or cell division cycle, is the cycle of events in a eukaryotic cell from one cell division to the next. ...
