C. the unlikelihood that a folded RNA template could form a cavity specific enough to fit only one given amino acid
D. the unlikelihood that a folded RNA template could directly interact with hydrophilic amino acids
The hypothesis that the genetic code consisted of groups of three nucleotides rather than groups of two nucleotides supports which of the following conclusions?
