The quick answer is that yes, you can determine whether you have ancestors who are Native American through your DNA. I don't know whether it would be enough to file for Native American heritage though.
What scientists would look at is your mitochondrial DNA (mtDNA) and, if you are a male, your Y chromosome. Even if you are not a male, you can look at your dad's, uncle's, or brother's Y chromosome to get an answer.
