  The origin of life is one of the greatest mysteries. The mechanism for the
synthesis of DNA is synonymous with the chemical origin of life, and theories
have been developed along many lines of reasoning, but resolving all
requirements remains a challenge, such as defining an objective path to produce
sequences of encoded nucleotides paired as adenine to thymine and guanine to
cytosine. Here, a new theory for the origin of DNA is presented. The theory is
based upon three lines of experimental evidence and agreement of structural
symmetry between DNA nucleotides and steroid hormones, and introduces a new
concept of synthesizing both structural and functional characteristics of DNA
at the same time within a single unified complex of interleaved tetra-ringed
structures, steroid molecules which form reaction vessels that serve as
co-enzymatic building blocks. The new theory indicates that the establishment
of the DNA nucleotide code is among the very first synthesis steps. Moreover,
as a consequence of the intermolecular synthesis of both structural and
functional characteristics within a unified complex, there is a culminating
process step that sets forth in motion both DNA and the steroid structures that
subsequently trigger replication and transcription, as well as protein
translation, thereby resulting in the instantaneous release of life function.
