The flag for nucleotides have two key elements in their design that relate to their properties: shape hydrogen bonding aspects. Although DNA models come in a variety of colours, these standards should set the standard.
With proper knowledge, the code of life can be stored in a data bank, like in an apple, or some other kind of forbidden fruit. Then, this data can be transmitted across the universe and if you had cloning vat in some other nearby star system, a clone of yourself could be made. Then with a cerebral quantum entanglement probe, you could remotely operate your distant body across space and time with enchanted dream synchronicity, like in James Cameroon's Avatar. With an entangled data drive receiver, information would be instantaneous. Thus you could visit another galaxy with an astral projection router. Which most likely has already been created by more advanced civilizations.
And just because we have an enhanced understanding of chemistry does not negate the magical properties of these molecules. As we have an advanced ability to manipulate these points of matter in the universe, their ultimate power is greater than the human brain can conceive. Alchemy is to chemistry as Astrology is to astronomy. Once upon a time chemistry touched the infinite power of knowing via Alchemy. Thus chemistry is entangled with alchemy, and fundamentalist objective atheists are usually filled with an ugly passion of a doubting Thomas to deny the mystical and unknowable aspects of chemistry, unless spoken through a PBS humanist overtone, of a non-localized deep thought tone, imploring the listener, with almighty poetic resonance for the evolutionary process from star stuff to evolution. Then only, will talk of objective scientific chemistry and astronomy have soulful resonance with Alchemy and Astrology.
