Mating of Yeast

The yeast Saccharomyces cerevisiae is a simple single celled eukaryote with both a diploid and haploid mode of existence. The mating of yeast only occurs between haploids, which can be either the a or α (alpha) mating type and thus display simple sexual differentiation. Mating type is determined by a single locus, MAT, which in turn governs the sexual behaviour of both haploid and diploid cells. Through a form of genetic recombination, haploid yeast can switch mating type as often as every cell cycle.

Famous quotes containing the words mating of, mating and/or yeast:

    The far-off clinching and mating of arches, the leap and thrust of the stone, carrying a great roof overhead, awed and silenced her.
    —D.H. (David Herbert)

    The elephant, not only the largest but the most intelligent of animals, provides us with an excellent example. It is faithful and tenderly loving to the female of its choice, mating only every third year and then for no more than five days, and so secretly as never to be seen, until, on the sixth day, it appears and goes at once to wash its whole body in the river, unwilling to return to the herd until thus purified. Such good and modest habits are an example to husband and wife.
    St. Francis De Sales (1567–1622)

    Do you not know that a little yeast leavens the whole batch of dough?
    Bible: New Testament, 1 Corinthians 5:6.
