DNA is cause of nuclear pore (hole between two nuclear membrane) appearance.
The single-stranded DNA located in pore annulus initiate nucleoporins assembly building native structure of pore complex ( please see details in Kuvichkin V.V., 2011, J. Membr. Biol. v. 241(3), pp.109-116).
No, a nuclear pore is a characteristic of the nuclear membrane. The nuclear membrane is a double membrane which envelops the nucleus, an organelle.

It's pretty much a pore in a nucleus.

Nuclear Pore
It's like a communication canal, DNA is isolated inside the nucleus but RNA can leave and go into the cytoplasm where it's transcribed through the pore. Water and other molecules can also go through.
Cell membrane, DNA(same with plant cells), ribosmes, cytoskeleton, microtubules, microfilaments, nucleus, nuclear envelope (a combination of nuclear pore and nucleolus), Golgi complex, mitochondrion, endoplasmic reticulum(rough and smooth), Lysosomes, vacuole, and Centrioles.

The analogy of a nuclear pore is that if it were a factory, the nuclear pore is like the wall around the manager's office. These walls contain all plans that tell the workers in the cytoplasm what to make and the quantity it should make.

The nuclear PORE membrane
Small holes in the nuclear membrane of a cell's nucleus, which allow the transportation of water solluable materials in and out of the nucleus through the nuclear membrane.
