  1. Standard deviation of X, Y, Z coordinates of phosphorus atoms for each residue were calculated as described in Methods. Coordinates were taken from the structure of the 70 S ribosome. Includes introns in 16 S and 23 S rRNA genes.
  2. 23 S rRNA nucleotides only.
  3. 16 S rRNA nucleotides only.
