Most of the information concerning recombination between repeated sequences has been derived from studies in the yeasts Saccharomyces cerevisiae and Schizosaccharomyces pombe,5 although some classes of ectopic recombination have also been studied in mammalian cells.6 The yeast studies indicate that the rates of ectopic recombination are surprisingly high (similar to the rates of classical recombination) and that the rates of these events are much higher in meiosis than in mitosis. Conversion events involving repeats on nonhomologous chromosomes are associated... [Pg.633]

Since the cofactors are not essential in S. cerevisiae, but the tubulin heterodimer is, it is clear that tubulin in this organism must be able to form heterodimers in the absence of cofactors. One possible explanation for this is that the sequences of the S. cerevisiae tubulins are the most divergent known. Saccharomyces cerevisiae cells contain only relatively simple microtubule arrays that participate in only three well defined and temporally distinct cellular process mitosis, meiosis, and nuclear fusion. Perhaps this reduced selective pressure on their tubulin genes has allowed the evolution of spontaneously dimerizing tubulin in this organism. [Pg.97]
