"Molecular biologist's dream"


"Molecular biologist's dream" is a phrase coined by Gerald Joyce and Leslie Orgel to refer to the problem of emergence of self-replicating RNA molecules, as any movement towards an RNA world on a properly modeled early Earth would have been continuously suppressed by destructive reactions.[47] It was noted that many of the steps needed for the nucleotides formation do not proceed efficiently in prebiotic conditions.[48]
