Embryonic development seemingly proceeds with almost perfect precision. However, it is largely unknown how much microscopic variability is hidden beneath this macroscopic accuracy. Here, we quantified
Background. Most methods for constructing aneuploid yeast strains that have gained a specific chromosome rely on spontaneous failures of cell division fidelity. In Saccharomyces cerevisiae, extra chro
Genetic control of pluripotent mammalian ES cells is determined by a transcriptional network, with a "central core" of transcription factors, Pou5f1, Sox2 and Nanog. Zebrafish homologues of the "core
