Electron transfer is an absolute necessity for basic life processes like the construction of DNA by RNA, photosynthesis, and respiration. No free elemental oxygen (O2) existed on Earth as far back in time as three billion years ago. All the iron on earth became oxidized when oxygen began to be produced by plant photosynthesis. Iron ore is oxidized iron. Oxidized iron cannot be used as a reactant in electron transfer by RNA. This research proves that RNA could have used iron to catalyze single electron transfer to produce DNA in an oxygen free world three billion years ago. The concept has been proposed but never proven experimentally until this new research accomplished the effect. The research shows that the basic building blocks of life and life processes could have developed very early on Earth and independent of the present day processes that produce DNA from RNA.
