- How is the mating type of a yeast cell determined?What is the difference between a haploid and a diploid eukaryotic cell?8) The diagram below represents a yeast cell that is in the process of budding, a form of asexual reproduction. Nucleus -Bud "Nucleus Which of the following statements describes the outcome of this process? A) The two cells that result will each contain half the species number of chromosomes. B) The two cells that result will have identical DNA. C) The bud will develop into a zygote. D) The bud will start to divide by the process of meiotic cell division.
- Why do cell biologists study yeast?A cell undergoing division has a haploid chromosome number of 15. Give the numerical value for each of the following: a) number of chromatids in a cell in anaphase of mitosisb) number of chromosomes in a cell in metaphase of mitosisc) number of homologous pairs in a cell in prophase of meiosis I d) number of chromatids in a cell in metaphase of meiosis IIe) number of centromeres in a cell in prophase of meiosis II f) number of centromeres following cytokinesis of meiosis IWhich cell is considered a haploid cell? (has half the number of chromosomes?) Why?
- What is the difference between a chromosomes and a chromatids? a) there is no difference they are the same b) chromatids is always one stand of dna chromosomes can be one or two strand depending on the phase of the cell cycle c) chromatids is always two strands of dna chromosomes can be one or two stands depending on the phase of the cell cycle d) chromosomes are homologous chromatids are identicalIs Neurospora haploid or diploid?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…
