The building blocks for nucleotide bases seem to be capable of forming in hot conditions, like those found around deep sea hydrothermal vents. Nucleotides are made of rings of carbon with nitrogen atoms in the ring structure. These rings were not thought to form easily in the cold conditions of the gas clouds in space, but may form readily in these hydrothermal vent conditions. On early earth this might of provided the building blocks for DNA and RNA molecules.
And...Happy Father's Day!
