Dokumentins

Dokumentins are a hypothetical class of organic molecules that have been proposed as potential components of a non-water-based life form. The concept, primarily explored in speculative astrobiology, suggests that these molecules could serve a role analogous to DNA or RNA in terrestrial life, carrying and transmitting genetic information. Unlike nucleic acids which rely on hydrogen bonding and a water solvent, dokumentins are envisioned to function in alternative solvents, perhaps highly nonpolar hydrocarbons or liquid methane.

The precise chemical structure of dokumentins remains undefined, as their existence is theoretical. Researchers considering such molecules focus on the general principles required for genetic material: stability, the ability to replicate, and the capacity to encode information. Hypothetical mechanisms for dokumentin replication might involve templating or self-assembly processes that differ significantly from biological processes on Earth. The stability of dokumentins would need to be suitable for the extreme temperatures and pressures found in environments where water is not present.

The study of dokumentins is primarily a thought experiment, pushing the boundaries of our understanding of what life might be like beyond Earth. It encourages consideration of alternative biochemistry and the universal requirements for life. While no direct evidence for dokumentins has ever been found, their conceptualization aids in the design of experiments and the search for extraterrestrial life that may not conform to Earth-centric models. The term itself is not widely established in mainstream scientific literature and is more often found in speculative discussions.
