Experiment: Page 6 de can exist stably in either a haploid or a diploid state. A haploid S. cerevisiae mes. When certain haploids come into contact, they fuse their cell walls and membranes, followed by the fusion of their nuclear membranes. The single nucleus now has 32 chromosomes, 16 from each parent strain, and is thus a diploid. Haploid yeast strains divide mitotically to give rise to haploid progeny, and diploid strains divide mitotically to give rise to diploid progeny. Certain haploids can fuse to form diploids. Haploid S. cerevisiae exists in two "mating types," called a and a Mating occurs only between a and a cells; no mating occurs between cells of identical mating type. We have a collection of eight a haploid mutant strains and eight & haploid mutant strains of yeast unable to synthesize tryptophan (trp). These will be combined (mated) in all possible combinations to yield diploid strains. If the diploids can grow on minimal medium, complementation occurred between the…
The figure below shows the life cycle of the fungus Neurospora. The adult stage of the Neurospora is a multicellular haploid: a. Between which two stages of the Neurospora life cycle do most mitotic cell divisions occur? b. Neurospora has an arginine amino acid synthesis pathway shown below: Suppose I have a neurospora strain that has a mutation such that it will not grow unless I supplement the media (food) with arginine (but not with citrulline or ornithine). What gene is mutated? Explain your reasoning. c. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not ornithine supplements. Assming genes A, B and C are unlinked and there is only one mutation per strain: i) What percentage of the progeny will grow on ornithine? ii) What percentage on citrulline? iii) What percentage on arginine? Show your work for i), ii) and iii). [Can be answered in less…
The plant Haplopappus gracilis has a 2n of 4. A diploid cellculture was established and, at premitotic S phase, aradioactive nucleotide was added and was incorporatedinto newly synthesized DNA. The cells were then removed from the radioactivity, washed, and allowed to proceed through mitosis. Radioactive chromosomes or chromatids can be detected by placing photographic emulsionon the cells; radioactive chromosomes or chromatids appeared covered with spots of silver from the emulsion.(The chromosomes “take their own photograph.”) Drawthe chromosomes at prophase and telophase of the firstand second mitotic divisions after the radioactive treatment. If they are radioactive, show it in your diagram. Ifthere are several possibilities, show them, too.

1. These questions will utilize yeast analysis and provide you with mock experimental data for the phenotypic analysis of yeast growth to infer genotypes. The following symbols indicate growth or no growth on medium lacking particular components (examples in 1A are medium lacking methionine "-MET" and medium lacking tryptophan "-TRP". Growth is indicated by a filled, black circle. No growth on a particular medium is indicated by an unfilled circle. In cases where we look viability of spores, we would use absence of a circle to indicate that a spore did not grow at all (for example, it inherited a lethal mutation). Growth No growth 1A. You have two haploid strains (Haploid of opposite mating types. Their genotypes and phenotypes are shown below. +MET - TRP - MET +TRP Haploid 1 MATA: MET2 trp3 Haploid 2 MATalpha: met2 TRP3 You cross each strain to a WT yeast and observe the following: Haploid 1 x WT= Growth on all three media shown above.
