Well, actually there are plenty of aliens that shouldn't have DNA in general. :) Petrosapiens, for example, NRG and Ra'ad. So, the term DNA clearly isn't used in the series in it's usual sense.

Probably the term DNA in Ben 10 used as an equivalent of "hereditary information of species in a broad sense"
