In the cell nucleus.

Mostly, RNA editing occurs in nucleus. RNA editing such as C to U deamination can be accompanied by APOBEC proteins in the nucleus. Insertion or deletion of bases also reported. In addtion, RNA edition known to occur in mitochondria and plastids.

in the nucleus of the cell when the mrna causes the DNA to spilt in two and then it Paris up with one side of the DNA and then the RNA goes back out into the cytoplasm

This is True! RNA editing is different than pre-mRNA processing, which takes place in the nucleus: Processing includes the removal of the introns (splicing), cleavage at the poly A site, and poly-adenylation. Then RNA translation is effected at the Cytoplasmic Ribosomes. RNA editing, which is different, has been shown to occur in the cytosol, the nucleus, and inside the mitochondria.

RNA is located in the nucleus of the cell and throughout the cytoplasm.

False. Mature RNA editing takes place on the spliceosomes in the nucleus of the cell before it is exported ti the cytoplasm. Introns cut out, exons spliced together.
