Short summary
We show that the fundamental molecules of life (those common to all three domains of life: Archaea, Bacteria, Eukaryota), including nucleotides, amino acids, enzyme cofactors, and porphyrin agglomerates, absorb light strongly from 230 to 280nm (in the UV-C) and have chemical affinity to RNA and DNA. This supports the "thermodynamic dissipation theory for the origin of life", which suggests that life arose and evolved as a response to dissipating the prevailing Archaean UV-C sunlight into heat.
