SSU rRNA from the bacterium Thermus thermophilus. This model corresponds to the bacterial core model which is indicated in figure 1a of the paper by solid black, green and blue helices.

LSU rRNA from the bacterium Thermus thermophilus. This model corresponds to the bacterial core model which is indicated in figure 1b of the paper by solid black and green helices. Helices B14, D6, E15 and E16, are not present in all bacteria. Note that helix D6 is present in the sequence determined by Hoepfl P., Ludwig W., Hartmann R.K., Ulbrich N., Schleifer K.H. (Nucleic Acids Res., 16, 9043-9043 (1988)). However, this helix was not found in the tertiary structure determined by Yusupov et al. (ref. 1 of the paper)

SSU rRNA from the yeast Saccharomyces cerevisiae. This model corresponds to the eucaryotic core model which is indicated in figure 1a of the paper by solid black, red, pink, and orange helices.

LSU rRNA from the eukaryote Saccharomyces cerevisiae. This model corresponds to the eucaryotic core model which is indicated in figure 1b of the paper by solid black, red, pink, and orange helices.

SSU rRNA from the amoeba Naegleria gruberi. This model has several extensions to the eukaryotic core, viz. helices 17\e1, 23/e5, 43/e1 to 43/e4 and 45/e1 (hollow red in figure 1a of the paper).

LSU rRNA from the moss Funaria hygrometrica. This model has one extension C1/e5 and C1/e6 with respect to the eukaryotic core.
