Fig. 3: Enantioselectivity indices for 15 ribozymes.
From: Prebiotic chiral transfer from self-aminoacylating ribozymes may favor either handedness

A Points show the median enantioselectivity index for each ribozyme listed. Error bars indicate 95% confidence intervals determined by bootstrapping the replicates from independent experiments (see Fig. 2) 1000 times. B The distribution of indices shows a range of positive and negative values, indicating both D- and L- selective ribozymes.
