Genetic Code vs Life

The genetic code is a string (double helix) of the four letters A, C, G and T (bases of DNA) acting as instructions to construct the chain of amino acids forming the protein molecules as the elements of organic life. There is here an obvious connection to a computer code for constructing words as sequences of letters.

But life is more than “just” the sequence of amino acids forming the protein molecules, namely the geometric forms of the corresponding protein molecules which determines their interaction as the expression of life. This is called protein folding and is a grand challenge in computational biology as a very complex Newtonian mechanics initial value problem with forces to be computed from quantum mechanical models consuming overwhelming computer power.

And more: life comes out as interaction of the (folded) protein molecules within the cell, between the cells of an organism, and between the organism and its surroundings including other organisms. This corresponds to an initial value problem of enormous complexity way beyond current computational capacity.

The first step to reduce computational work is to find a quantum mechanical model which avoids the high dimensionality of standard models. Real Quantum Mechanics offers a step in this direction with a non-standard quantum mechanical model as a system in three dimensions. Take  a look. The enigma of mechanics is the computation of forces. See 22. Atom Physics under Model Workshop with RealQM Atom Simulator as start.
