Figure 6-20A comparison of the structures of procaryotic and eucaryotic ribosomes
Ribosomal components are commonly designated by their "S values," which indicate their rate of sedimentation in an ultracentrifuge. Despite the differences in the number and size of their rRNA and protein components, both types of ribosomes have nearly the same structure and they function in very similar ways. Although the 18S and 28S rRNAs of the eucaryotic ribosome contain many extra nucleotides not present in their bacterial counterparts, these nucleotides are present as multiple insertions that are thought to protrude as loops and leave the basic structure of each rRNA largely unchanged.
