They found that in a racemic mixture, an excess of D or L amino acids results in longer, sturdier polymers that don't break down as readily when exposed to hazards such as hydrogen peroxide, and that amino acids delivered by meteorites were slightly biased towards being L and thus catalyzing longer D nucleotide sequences.
