Five of the seven groups in this Laboratory study mechanisms of gene regulation, chromosome condensation and segregation, and the transposition of retroelements in the unicellular eukaryotes Saccharomyces cerevisiae and Schizosaccharomyces pombe. Because of the powerful genetic tools developed for these yeasts, they are excellent model systems for studying basic processes common to all eukaryotic cells. more > Laboratory Chief: Alan G.
