Essay

Cellular processes are often regulated by unknown mechanisms.In many cases, biologists work backward in an attempt to understand a process in which they are interested.This was the case when Nurse and Hartwell were trying to understand how cell division is controlled in yeast.Describe the process by which they "broke" the system and then supplied the "missing parts" to get the cell cycle running again.What further evidence did they collect to show that human cells and yeast cells regulate the cell cycle using a similar mechanism?
