Today I learned about the use of certain organisms being used as pinnacles of research.
Mus Musculus
Gallus Gallus
Xenopus Laevis
Danio Rerio
Caenorhabditis Elegans
E. Coli
And Yeast. And not just one kind. But TWO.
One kind (Saccharomyces cerevisiae) reproduces through budding, because they are spherical. (this is the baker's yeast)
The other (Schizosaccharomyces pombe), which is cylindrical, reproduces through gaining length and then pinching off, so two organisms form.
Yeast is extremely fucking useful for cell cycle research.
