Three new physics realizations of the genetic code and the role of dark matter in bio-systems

Abstract

TGD inspired quantum biology leads naturally to the idea that several realizations of genetic
code exist. Besides the realizations based on temporal patterns of electromagnetic �elds I have
considered three di�erent new physics realizations of the genetic code based the notions of many-
sheeted space-time, magnetic body, and the hierarchy of Planck constants explaining dark matter
in TGD framework.
1. The �rst realization - proposed in the model for DNA as topological quantum computer (tqc)
- maps the nucleotides A,G and T,C to dark quarks u,d and their anti-quarks assignable
to the ends of magnetic
ux tubes representing braid strands and connecting nucleotides to
lipids of cell membrane.
2. Second realization was discovered in the model of dark nuclei as strings of dark baryons.
Dark baryons realize codons in terms of quantum entanglement and without decomposition
to letters. Dark baryons are strings of 3 quarks connected by two color
ux tubes. The
neutral states of the dark baryon predicted by the model are in 1-1 correspondence with
DNA, RNA, aminoacids. Candidates for the counterparts of tRNA anticodons are also
obtained if one accepts that genetic code actually decomposes to 2 steps 64 ! 40 ! 20 such
that there are 40 dark baryon counterparts for tRNA anticodons. The amazing �nding is
that vertebrate genetic code comes out correctly.
3. The third realization is a physical realization for the divisor code proposed by Khrennikov
and Nilsson. The realization relies on two integers labeling magnetic
ux tubes containing
dark matter. The dark magnetic
ux tubes assignable to DNA codons and amino-acids
could be labeled by these integers providing a representation of the genetic code consistent
with the divisor code. Also a physical mechanism implying the physical equivalence of the
dark baryon code and divisor code can be imagined.
The basic proposal is that dark baryon counterparts of basic bio-molecules and genetic code
were present from beginning and gave rise to pre-biotic life at the magnetic
ux tubes so that the
evolution of biological life meant the development of translation and transcription mechanisms
allowing to transform dark baryon variants of the codons to their chemical variants. These
mechanisms would be still at work inside the living cell and allow the living matter to perform
genetic engineering. This proposal is consistent with recent �ndings about large variations of
genomes inside organism.
There is a strange experimental �nding giving support for this picture. A water solution
containing human cells infected by bacteria is sterilized by a �ltering procedure and healthy cells
are added to the �ltrate. Within few weeks the infected cells re-appear. A possible explanation is
that dark baryon variant of the bacterial genome realized as nano-sized particles remains in the
solution despite the �ltering.
The codes are discussed from the point of view of DNA as tqc hypothesis and the model for
protein folding and bio-catalysis. The basic selection rules of bio-catalysis could be based on the
two integers assignable to the dark magnetic
ux tubes. Only bio-molecules whose dark magnetic
bodies contain a layer characterized by same integers can be connected by dark magnetic
ux
tubes. The reconnection of the dark magnetic
ux tubes selecting the bio-molecules participat-
ing the catalytic reaction and the contraction of these
ux tubes induced by a phase transition
reducing Planck constant and forcing the bio-molecules near to each other would represent basic
mechanisms of bio-catalysis.
