Since there is no sequal to GATTACA, they basically just leave it up to your imagination to come up with the rest.
This same cinematic logic was put into place with the movie, "The Client". At the end, you are left you imagine for yourselves what you wish happens.
I hope this helped! Have an amazing day :)
I'd say that it is incorrect because each carbon atom should bond 4 times and all three carbon atoms in this structural formula only bond once. The reverse is true for hydrogen atoms. They only form one bond but in this structural formula two of them have four bonds. I don't know about nitrogen though.
I found plenty on why there are different. if you would like a sarcastic answer I would suggest "they both keep swimming, swimming, what do we do we keep swimming swimming. "
