To Whom This May Concern :

	I have a question pertaining to methylene blue.  I'm a biology
student in
Upstate New York, and one of the questions I have to explain is the
following
:

When living yeast cells were placed in congo red dye and examined under
the
microscope, the yeast cells remained colorless.  However, when placed in
methylene blue, they became blue.  Later, dead yeast cells were placed in
congo red dye.  These cells turned red.  Explain these three
observations.

Do you have an answer for this question? Thank you very much for your
time and
consideration. I hope to hear back from you as soon as possible.
