A single dna molecule is too small to see with the naked eye, but a few million dna molecules released from a few million microbes is easy to see IRL. In my bio lab days we did an experiment to isolate the dna molecules from a scoop of microbes, and at the end you wind up with a clump of dna molecules that together are about the size of an eraser head.
And yeah as the other person said, the term “staining” is the official term used for what you’re calling “tagging”

What does DNA feel like? Smell like?
I don’t remember, it was a long time ago. But I’m sure a biology major or professional biologist could answer your question
