I am currently reading a book called The Spiritual Genome by Brad Bartholomew. In the book he talks a lot about the ability of DNA to absorb and emit Biophotons which are a very weak photons given off by biological systems. They think that Biophotons are used to transmit information within and between cells through microtubules which are perfectly suited for transmission of Biophotons in the UV range. DNA could also be used to store binary data by flipping the spin of the valence electrons in the outer-shells of atoms in the DNA. This could possibly be how "memory" for inherited instincts are stored in the DNA, because each outer-shell of an atom has 4 orbitals that can each hold 2 electrons of opposite spin for a total of 8 quantum bits of information (qubits).
I'm only part way through his book, but so far it's very interesting...
