Question

Scientists were studying yeast cells in which a mutation inactivated a gene required for cell division. Without this gene—and the protein it encoded—these mutant yeast cells were unable to divide normally. But the scientists discovered that introducing a related protein from human cells could "rescue" these mutant yeast cells, allowing the cells to resume normal division. Based on this finding, what is the most likely conclusion you could make?.

Answer 1

Based on the finding that introducing a related protein from human cells could "rescue" mutant yeast cells, the most likely conclusion is C. The proteins that control cell division in yeast and humans are functionally equivalent and have been conserved, almost unchanged, for more than a billion years.

What conclusion can be made from the research?

The yeast cells are unable to reproduce or divide normally due to a mutation and yet when when a human cell protein is introduced in the yeast cell, they are able to procreate once more.

What this shows is that the proteins in the cells of humans and yeast cells that facilitate cell division have remained the same for over a billion years. We come to this conclusion because the same protein which works in humans can work in the yeast cells. This shows that the cells are equivalent or the protein would not have worked.

Options for this question are:

• A. Yeast cells require human proteins to divide.
• B. Modern humans most likely obtained their cell-division proteins from ancient yeast.
• C. The proteins that control cell division in yeast and humans are functionally equivalent and have been conserved, almost unchanged, for more than a billion years.
• D. Yeast cells most likely obtained their cell-division proteins from the cells of early humans.
• E. Yeast and humans diverged from a common ancestor much more recently than previously thought, perhaps fewer than a million years ago
