A.1 An Overview of Yeast in the Laboratory Yeast geneticists have gathered enough information on S. cerevisiae to state with confidence that single-celled eukaryotes such as yeast express genes, organize themselves, perform biological functions, and differentiate using variations of the same processes found in multicellular eukaryotes. Yeast has proven to be an excellent model for the study of cell cycle control and for the dissection of eukaryotic signal transduction pathways. Using standard genetic analyses and newly developed genomic tools, yeast researchers continue to provide critical insights into basic cellular processes. 1 har06584_refA_001-020 2 11/4/06 10:09 AM Page 2 Reference A Saccharomyces cerevisiae: Genetic Portrait of a Yeast Figure A.1 Yeast cells.

The Yeast Life Cycle Yeast cells alternate between haploid (1n) and diploid (2n) phases in which new daughter cells arise mitotically as buds that grow in size and eventually split from the mother ce...
