Hm. The ninjutsu Kabuto uses to manifest the Sound Five and Orochimaru from his body is a senjutsu / ninjutsu called, which I believe is supposed to sound like "DNA." The kanji literally means "tradition strange distant shadow," and could be roughly be interpreted as "the strange shadows passed down over a long time."

I'll have to look into this entry in greater detail.
