and 5S rRNAs. These rRNAs play a role in peptide bond formation and translocation. The rRNA molecules fold into complex secondary and tertiary structures, forming domains and motifs that are essential ...

Ribosomal RNA (rRNA) molecules were initially characterized ... of rRNA gene that encodes three distinct RNA species: the 23S, 5S, and 16S rRNAs. In comparison, eukaryotic cells contain two ...

messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Although some RNA molecules are passive copies of DNA, many play crucial, active roles in the cell. For example, some RNA ...
