It’s also worth noting that it’s possible to store data in the DNA of living cells — though only for a short time. Storing data in your skin would be a fantastic way of transferring data securely…
The RNA world hypothesis proposes that self-replicating ribonucleic acid (RNA) molecules were precursors to current life based on deoxyribonucleic acid (DNA), RNA and proteins. RNA is able both to store genetic information, like DNA, and to catalyze chemical reactions, like an enzyme protein. It may therefore have played a major step in the evolution of cellular life.
The RNA world would have eventually been replaced by the DNA, RNA and protein world of today, likely through an intermediate stage of RNP enzymes such as the ribosome and ribozymes, since proteins large enough to self-fold and have useful activities would only have come about after RNA was available to catalyze peptide ligation or amino acid polymerization. DNA is thought to have taken over the role of data storage due to its increased stability, while proteins, through a greater variety of monomers (amino acids), replaced RNA's role in specialized biocatalysis.
