If so, the RNA will have few double-stranded regions. The Ribosomal RNAs (rRNAs) and transmit RNAs (tRNAs) exhibit substantial secondary structure, as do some messenger RNAs (mRNAs).
figure: An example of self-complementarity in RNA, forming an internal double-stranded region; hydrogen bonding between bases is shown by the symbol •.
