Fungi as Genetic Model Organisms
Captions available
The idea
Yeast and bread mold serve as eukaryotic model organisms in genetics research, since their cells process and modify proteins much like human cells.
In practice
Neurospora crassa, the red bread mold, contributed foundational genetics discoveries; many genes studied in yeast have human counterparts.
Where people slip
A yeast model works because it is eukaryotic like its human counterpart — a bacterial model lacks the same internal membranes.
