It reforms a double stranded DNA molecule.

Technically the RNA polymerase copies DNA to make mRNA.

It stays in the nucleus until the cell next undergoes mitosis or meiosis. The nuclear DNA is like a reference only library book- you can make a photocopy (mRNA) but cant take the book out of the library (the nucleus), where it stays to be copied again for / by something else
