Complementariedade (bioloxía molecular): Diferenzas entre revisións

By assigning suitable ([[Ambigram|ambigraphic]]) characters to complementary bases (i.e. guanine = ''b'', cytosine = ''q'', adenine = ''n'', and thymine = ''u''), it is possible to complement entire DNA sequences by simply rotating the text "upside down".<ref name=rozak1>{{cite journal |author=Rozak DA |title=The practical and pedagogical advantages of an ambigraphic nucleic acid notation |journal=Nucleosides Nucleotides Nucleic Acids |volume=25 |issue=7 |pages=807–13 |year=2006 |pmid=16898419 |doi=10.1080/15257770600726109 |url=http://www.tandfonline.com/doi/abs/10.1080/15257770600726109?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%3dpubmed}}</ref> For instance, with the previous alphabet, ''buqn'' (GTCA) would read as ''ubnq'' (TGAC, reverse complement) if turned upside down. This feature is enhanced by proposing custom fonts rather than ordinary ASCII or even Unicode characters.<ref name=rozak2>{{citeFlower, R. H.; Knoll, A. H.; Yuan, X. (1955).
