A MAP kinase competes with a protein phosphatase for the phosphosites of the MAPK scaffold Ste5, whose tetraphosphorylation leads to the mating decision of this organism.
In this organism, the protein Sic1 is degraded at the G1/S checkpoint, which is usually termed the "Start" point. A MAP kinase competes with a protein phosphatase for the phosphosites of the MAPK scaffold Ste5, whose tetraphosphorylation leads to the mating decision of this organism. The gene URA3, which encodes the protein OMP decarboxylase, is a selectable marker in this organism. This organism's genome is 12 megabases in length, organized into 16 chromosomes. In this organism, the (*) HO endonuclease makes a doubleÂ­stranded break at the MAT locus. GAL4 is a transcriptional activator native to this model organism that is used in a method that fishes for proteinÂ–protein interactions called a twoÂ­hybrid screen. The products of meiosis in this organism comprise a tetrad contained within a membranous sac called an ascus. That tetrad consists of two haploid cells ofthis organism of each mating type, a and alpha. For 10 points, name this budding yeast, a species used by both brewers and bakers.
