Abstract
Interactions between RNA molecules have been postulated to play an important role in the assembly of ribosomes. Using the sequence analysis and the search of continuous complementary regions on 16S rRNA and 23S rRNA, the recognition sites involved in the formation of ribosome of E.coli are postulated. The number of postulated sites was narrowed down by taking available experimental data. The suggestive evidence for correct postulation is obtained from sequence comparison studies of 16S and 23S rRNAs from various species. The sites 891–899 and 1195–1203 on 16S rRNA along with the corresponding complementary sites 1904–1912 and 760–768 on 23S rRNA are predicted to be the most probable candidates for the sites of recognition between 16S and 23S rRNAs. The possibility of the involvement of the additional site 630–638 on 16S rRNA with its complementary site 2031–2039 on 23S rRNA cannot be ruled out.
