Study shows adding UV light helps form 'Missing G' of RNA building blocks

ause most aspects of the process were likely to occur on the early Earth and it reduces chemical constraints."

The authors suggest that aqueous pools containing small amounts of formamide may have existed on the early Earth. During hot and dry periods, water evaporation could have given rise to concentrated solutions of formamide and exposed mineral surfaces coated with formamide.

By conducting additional experiments at 100 degrees Celsius with solutions of formamide and water, the researchers confirmed that this "drying pool" model could give rise to solutions of formamide capable of producing the compounds found in their earlier experiments.

"While there is still a lot of chemistry required for us to better understand the formation of biological molecules needed for life, these one-pot reactions that occur due to the synergy of thermal and photochemical processes tell us that the chemical and environmental requirements to produce life are probably less restrictive than we once thought," added Hud.
