Question

35. the identification and study of genes important for the cell cycle us budding yeast has provided great insight into our understanding of the unregulated cell cycle in cancer cells. why is budding yeast such a useful model system for studying the cell cycle?

a. as budding yeastp progress through the cell cycle, they naturally express a GFP tagged protein that is visible by flourescene microscopy

b. the genes involved in the cell cycle is budding yeast are very different from the human genes involved in the cell cycle.

c. it is easy to visualize yeast by scanning electron microscopy which is a helpful tool fir performing genetic screens

d. the cell cycle budding yeast can be easily visualized using a light microscope and mutants with defects in the cell cycle genes can be easily isolated.

Answer 1

the cell cycle budding yeast can be easily visualized using a light microscope and mutants with defects in the cell cycle genes can be easily isolated.

option D is correct.

Scanning electron microscopy is used only for surface analysis.

budding yeast is used because it is haploid and the genes for cell cycle is almost similar in human and yeast. Since it is haploid mutation effect on the cell cycle can be easily seen by mutating the gene (contains only one copy).
