What have we learned about RNA structure and function so far ... Prokaryotic organisms contain one type of rRNA gene that encodes three distinct RNA species: the 23S, 5S, and 16S rRNAs.

Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...
