Actually, the technical reason is the Dioxy. The nucleus wall is impermiable to this molecule which is why DNA is translated to RNA. There are other reasons why DNA does not leave the nucleus. First, the chemical reactions necessary for protein translation are still random, so they are more likely to occur in a smaller area of space. Separation of DNA allows RNA to better contol protein production since you can have mutliple copies of RNA.

In eukaryotes, DNA is found in the nucleus because there are many enzymes and other chemicals in he cytoplasm that may damage the DNA. However, mitochondria have their own DNA which is not in the nucleus.
