Hybridization of nucleotides within RNA molecules allows for the formation of ''secondary structures'' such as RNA hairpins, these secondary structures give RNA molecules an overall ''tertiary structure'' which is often essential for the RNA to perform its function.  Additionally, RNAs can hybridize through base pairing with other RNAs or with complementary DNA sequences.

==Function==

 +
RNA performs a wide variety of functions within the cell.  Types of RNA are specified by the functions that they perform.

===mRNA===
 +
 +
''Messenger RNAs'' ([[mRNA]]) are the template molecules which are ''translated'' into [[protein|proteins]] by [[ribosome|ribosomes]].  They are generally synthesized by [[transcription]] of a DNA template (a [[gene]]) by [[RNA polymerase]], although some viral mRNAs are directly transcribed from an RNA template.

In [[eukaryote|eukaryotes]], nascent RNA transcripts must generally be processed from ''pre-mRNA'' into mature mRNA, via ''RNA processing'', before they are exported from the nucleus to be translated into proteins.
