It is designed to protect good bacteria in the gut.
I THINK:
The DNA strands unwind, and
RNA polymerase binds to the
template strand.
The tRNA moves through mRNA
with the activated amino acids
attached to it.
The synthesis of mRNA begins.
The amino acids assemble
to form peptide.
The mRNA undergoes intron
splicing and exits the
nucleus.
(sorry in advance if it's wrong)
The biggest issue would probably be number I. The other concerns (II, III, IV, V) would probably be easy to solve with the some specific chamber characteristics.
The fact that the moon has no atmosphere it means that it doesn't retain neither

nor

. Even with the appropriate chamber characteristics to retain such gases, how would the crop in the first place have so much free

to use.
Temperature could be managed inside the chamber as well as accelaration. The period of day light would be long and intense. As for the water, once plants evaporate water when they breath at night (instead of doing photosynthesis), that water could be all collected and condensed by the chamber to be used again during the day light period.
