B.P. Tu et al., ?Logic of the yeast metabolic cycle: temporal compartmentalization of cellular processes,? Science, 310:1152?8, Nov. 18, 2005.Cells grown in continuous and nutrient-limited conditions exhibit periodic metabolic cycles accompanied by a synchronized expression of most of their genes in three consecutive waves. This temporal compartmentalization might optimize key metabolic and cell-cycle processes and could be the origin of circadian and ultradian oscillators.Jürg
