Color stains may be used so that the yeast cells are easier to see.

If two proteins bind to one another, he said, the yeast cell where this happens turns blue.

Methylene blue is used to test for the presence of live yeast cells.

The yeast cells can then be seen with a microscope.

Yet the bacterium, the yeast cell, and we all are just physical systems.

Normally there aren't enough of the yeast cells to cause problems.

It is also simple to test drugs and interventions first in yeast cells.

These include dead yeast cells that are used as protein.

He discovered that a yeast cell produced about 1,000 vibrations a second.

Then, the dead yeast cells drift to the the bottom of the barrel or tank.
