As the turn ends, the other creatures revert to what they were before. If two Nanogene Conversions are cast on the same turn, they'll both wear off at the same time.
Nanogene Conversion
If the targeted creature is itself copying a creature, each other creature will become whatever it's copying, as modified by that copy effect.
This effect can cause each other creature to stop being a creature. For example, if you target an animated Vehicle, only the printed wording will be copied—the crew effect that is making it a creature until end of turn won't be copied. Each other creature will become an unanimated copy of that Vehicle.
