Some virus [[genome]]s are composed of DNA, such as that of the [[influenza]] virus.

DNA changes account for differences between individuals. However, they can also cause medical problems such as [[cancer]]
DNA changes account for differences between individuals. However, they can also cause medical problems such as [[cancer]]. Such DNA-based diseases can be inherited.
DNA is [[transcription|transcribed]] into [[mRNA]], which is in turn [[translation|translated]] into [[proteins]] built from [[amino acids]]. Additionally, DNA maybe transcribed into functional RNAs (ribosomal and transfer RNA) that do not undergo translation. [[RNA]] can also be reverse-transcribed back into DNA, which is the called [[Complementary DNA]] or [[cDNA]].
