I don't think that the pollen or spores metaphor is apt. Pollen and spores contain the genetic information required to produce the organism. Uracil on its own does not. My understanding is that there is tentative evidence that certain nucleobases may have originated from outside this solar system. This doesn't mean that these nucleobases were replicating when they got here (the function of pollen or spores).
I guess I'm more interested in how life began than how the compounds that allowed for life got here.
