[[Prokaryotic DNA]] is circular (a closed loop), while [[Eukaryotic DNA]] is linear (with ends) with the exception of [[Mitochondrial DNA]], which is circular too. DNA in [[prokaryote]]s usually consists only of one closed loop chromosome.<ref>Campbell, Neil A, et. al. ''Biology''. 6th ed. San Francisco: Benjamin Cummings, 2002. 299, 530-31.</ref>

DNA changes account for differences between individuals. However, they can also cause medical problems.

DNA is [[transcription|transcribed]] into [[RNA]], which is in turn being [[translation|translated]] into [[Amino Acids]] that that are used to form [[protein]]s which are the building blocks of all living creatures. [[RNA]] can also be reverse-transcribed back into DNA, which is the called [[Complimentary DNA]] or [[cDNA]].

DNA is [[transcription|transcribed]] into [[mRNA]], which is in turn being [[translation|translated]] into [[proteins]] from individual [[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 [[Complimentary DNA]] or [[cDNA]].
