You have isolated a strain of mutant yeast cells that divide normally at 25 degrees Celsius but cannot ente4 M phase at 37 degrees Celsius. You found that the gene for M cdk is not mutated. Which of the following temperatures sensitive mutations could be responsible for the.behavior of this strain of yeast? Inactivated of an enzyme that normally degrades m cyclin; Inactivated of a protein that normally triggers the synthesis of m cyclin; Inactivated of a protein kinase that normally Inactivate the cdk; none
2. Which of the following statements about the anaphase promoting complex is false? It promotes the degradation of proteins that activates mitosis; it inhibits m cdk activities; it becomes active at the very beginning of metaphase; it is activated by m cdk
3. During cancer development:.? Cells accumulate mutations in a fixed order which results in increase rate of cell division; the inheritance of mutations caused by dna damage is essential for cancer progression; there is typically…

ze the results of experiments that investigate nutritional requirement of
several mutant strains of yeast. The mutations in these strains cause a nutritional requirement for an
amino acid, such that the strains will not grow in media that lack one specific amino acid. Any mutant
that has a nutritional requirement is called an auxotroph, and is incapable of growing in a "minimal
medium" containing only a carbon source (e.g., glucose), a simple nitrogen source (e.g., ammonium
sulfate), and various salts and minerals. Such strains can be supported on a medium supplemented
with only the missing nutrient or on a "rich" medium that contains amino acids, vitamins, nitrogenous
bases, etc. (often in the form of an extract from yeast). The wild-type individual that can synthesize
the metabolic component is a prototroph, and is capable of growth on minimal medium.
The mutant strains in this activity are unable to synthesize tryptophan, lysine, or histidine;…

- Mutations in genes that change their pattern of expression (the time and cell type in which the gene productis produced) are thought to be a major factor in the evolution of different organisms. Would you expect thesame protein to work in the same way (for example, toperform the same kind of enzymatic reaction) in twodifferent types of cells (for example, cells in the retinaof the eye and muscle cells)? Is it possible that the sameprotein might function in different biochemical pathways in eye cells and muscle cells even if the protein’sbasic mechanism always remains the same?arrow_forwardoslorGulolaculGACu When does DNA replication occur in the cell cycle?

In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro.
