Do You Need DNA?

I never gave much thought to DNA centers. I've used them for animals, but never had to find one to get DNA info on people. My daughter had to seek dna experts to get her ex-husband to pay child support. There are many great reasons for looking for expert advice and results. That's something interesting for writers too. It would make a really interesting plot, or sub-plot in a storyline. Maybe that would be a good story to write. What is really interesting is how easy it is to get DNA information. You don't need much. Hair (with root), blood, of course, and even saliva. Hair is the easiest though.
