FIGURE 3.

Autoradiograms obtained after chemical footprinting of the ribosomal complexes shown in Figure 1. (A,B) 28S rRNA footprints after treatment with hydroxyl radicals and benzoyl cyanide, respectively; (C) 18S rRNA footprints after treatment with benzoyl cyanide. rRNA positions are indicated on the top, lanes 1–8 correspond to complexes shown on Figure 1, and lanes K represent the results of primer extension on rRNAs isolated from untreated ribosomes. Positions of reverse transcription stops are indicated with arrows.
