* It's not a natural occurrence: Bacteria don't normally have functional frog DNA.

* Genetically modified organism (GMO): If a bacterium had functional frog DNA, it would be considered a genetically modified organism (GMO). This is because the frog DNA was artificially introduced into the bacterium.

So, the answer is that the bacterium would be classified as a genetically modified organism (GMO).

However, it's important to note that there are many ethical and scientific considerations around creating such an organism.
