How Daughter Is Different From Mother ... In Yeast Cells

Scientists know how mother and daughter can be so different. Mother and daughter yeast cells, that is. The researchers have discovered a new mechanism for cell fate determination -- how one cell, the daughter, becomes dramatically different from the mother, even though they have the same genetic material.

The study shows why mothers and daughters differ in how they express their genes: a certain gene regulator gets trapped in the daughter cell's nucleus.
