The inverse fine-structure constant 1/α= 137.035 satisfies 1/α = 112 + 42 + 0.035 = 121 + 16 + 0.035 = 137.035, with 11 being the 11 dimensions of M-theory, 4 the number of dimensions of Einstein’s space-time, and 0.035 the 3.5 percent visible Universe. Cosmological information appears to be encrypted linearly as a triplet code in 1/α.

Abstract The molecular structure of ribosome binding sites of ten phage genes and two messengers of Escherichia coli were compared concerning the signation parts which are presumably used by ribosomes for recognition and binding. With a simple calculation based on triplet patterns sofar unknown agreements between all of these sequences were found. In several cases it was shown that agreements between old sequences are easier reognizable if the purine-and pyrimidine bases are put into the triplets instead of the four A, G, C, and U (T) bases. In such cases “homologous” parts of sequences were recognized with more distinctness. This is true in our case for the double triplet (hexaplet) py-pu-pu-pu-pu-(pu) and the binding site triplet py-pu-pu, which are preceding the ini­tiator. These triplets are in specific positions in all twelve sequences which were compared. The different course of the quaternary and the binary conformity curves (diagram 1) may show for the investigated area that the RNA phage gene-part is organized according to the well known quater­nary triplet code. On the contrary the phage φ-gene-part seems to be organized according to a more simple, binary triplet sequence of purine and pyrimidine bases. The binary sequence seems to be the more original, the quaternary the derived one.
