Now, scientists at Washington University School of Medicine in St. Louis report they have developed a model of gene expression in yeast that predicts with a high degree of accuracy whether a gene will be switched on or off. Different genes operate in each cell type at different times, and this careful orchestration is what ultimately distinguishes a brain cell from a liver or skin cell.
