Saccharomyces cerevisiae is a species of yeast commonly used in research and industrial applications. It is a unicellular eukaryote that is used as a model organism in biology due to its genetic similarity to higher organisms and its ease of manipulation in the laboratory. Research on Saccharomyces cerevisiae has contributed to our understanding of fundamental biological processes such as DNA replication, cell cycle regulation, and protein synthesis. Additionally, it is also used in the production of a variety of products such as bread, beer, and wine.
