Transcription: The biological clock experiment provided scientists with information about a cell's internal timing mechanisms and how they are affected by zero gravity. The investigation had broad implications because biological clocks are universal to all living things. Astronauts conducted the experiment by studying the growth of ordinary bread mold, or neurospora. When neurospora grows in a constant and uniform environment, the mold cycles rhythmically between different different growth stages. Each cycle of growth ends after 21 hours. Scientists believe that this interval was controlled by an internal cl ...
