How does dna content change as budding yeast cells proceed through meiosis? when nutrients are low, cells of the budding yeast (saccharomyces cerevisiae) exit the mitotic cell cycle and enter meiosis. in this exercise, you will track the dna content of a population of yeast cells as they progress through meiosis?

Ans.

When a yeast cell enters into meiotic cell division, the resulting daughter cells would contain half of the DNA as present in the parent yeast cell. This is because, meiosis results in formation of four daughter cells from a single parent cell and each cell has half of the amount of genetic material as present in parent cell. During meiosis, if a parent cell has 2n DNA, it would first doubles its DNA content (4n), then divides it equally to four daughter cells and thus, each cell contains half of DNA of parent (n).

Hence, the DNA content will become half when a yeast cell shows meiosis.
