It doesn't matter if anodites don't have DNA. A sonorosian (Echo Echo) is composed of sentient sound waves which, by definition, do not have DNA. So the Omnitrix could turn the user into an anodite the same way it can turn them into a sonorosian.

In fact, it doesn't make sense for several aliens to use DNA due to their dramatically different biology. DNA does not generically refer to any form of genetic information, but only to the deoxyribonucleic acid used by all life on Earth.

Petrosapiens, for example, as silicon-based, so their nucleic acid analogue would not be DNA. It would be, I don't know, petronucleic acid (PNA) or something. Same goes for pyronites, since they are clearly too hot to be carbon-based.
