chromex

The CHROMEX-01 experiment was designed to determine whether the roots of a plant develop similarly in microgravity and on Earth. One objective was to test whether the normal rate, frequency, and patterning of cell division in the root tip can be sustained in microgravity. Another objective was to determine whether the fidelity of chromosome partitioning is maintained during and after flight.
