Date: 6.10.2009
If you want to know how a cell responds to a particular chemical, the experiment is simple: Inject it with that chemical. Micropipettes — tiny needles that can puncture a cell and deliver a compound directly into it — are used precisely for this purpose. But biologists who study yeast have not had this tool available to them. A **yeast** cell’s rigid outer wall is too strong to be penetrated.
Because its processes of growth and division are similar to those of mammals, yeast is a useful model organism for cell biologists, particularly those studying the cell cycle.
