  • SummaryThe evolution of genetic material can be divided into at least three major phases: first, genomes of “nucleic acid-like” molecules; secondly, genomes of RNA; and finally, double-stranded DNA genomes such as those present in all contemporary cells. Using properties of nucleic acid molecules, we attempt to explain the evolutionary transition from RNA alone as a cellular informational macromolecule prior to the evolution of cell systems based on double-stranded DNA. The idea that… CONTINUE READING
