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

[[Mutation]]s in DNA accumulate over time and build up to create differences between organisms. Most mutations in DNA are harmless and don't affect the external appearance of the organism. Others can have beneficial effects, but some can disrupt important functions. Many diseases such as Autism and Ellis-van Crevice syndrome have been shown to occur due to these harmful genetic mutations.

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 such as ribosomal (rRNA) or transfer (tRNA) that do not undergo translation. [[RNA]] can also be reverse-transcribed back into DNA, which is the called [[Complementary DNA]] or [[cDNA]].
