The Symmetry of Uracil Translated into a Model Energy Genealogy

submitted by: hsrikm
Though synthesis of Uracil is not possible to accomplish from its' naturally apparent parts it is physically divisible into two symmetrical fragments that are mirror images of one another. A model is presented in animated form that associates a transparent energy divide to this situation as a basic universal parity that enables the existence of the cell as a genetic transmission, relates nucleic acid structure to a transparent energy scale that is based distances along a mobius...
