The cell without DNA will not survive, and the cell with two copies of the genome probably also will not be perfectly healthy. However, this is extremely rare if it even occurs, because Anaphase does not occur until the chromosomes are all lined up and attached at the centromere on the metaphase plate. It's more common to have like 1 chromosome accidentally go in teh wrong cell.

When a cell prepares for mitosis i.e. it makes copy of itself the cell must first copy its DNA. During the replication cells have an enzymes which split the double helix into two pieces. Another two enzymes, actually types of RNA come and attache themselves to the two strands an begin moving down the strand. As the move down they read the DNA and attach the necessary complementary letters, A G T or C to match the original strand. The RNA enzymes do down the whole two strands and when they are done the cell has two complete sets of DNA. Each New set containing one strand from the old set.

Well, then the cell with no DNA will end up dying or be destroyed by the immune system (should be phagocytes, I think). Without DNA, the cell cannot function. It cannot make protein, and cannot do anything they're supposed to do, because the instructions come from the DNA, without it, they're lost.

The other cell, with 2 DNAs, however... I guess it would be destroyed, too, I think (I'm not too sure), because it's unnatural (mutation! though not necessarily a bad thing), and the body has ways to check for these kind of things.

The cell without DNA will not be alive.

Also if both sets go into one cell there is very little chance of living either.
