What organism's cell lacks a nucleus?

I think all animals have at least some cells with nuclei. But for sure, red blood cells do not have a nucleus. That's why when people test for DNA from blood they have isolate the red and white blood cells.

Human blood cells, like all human cells, are eukaryotic. However, red blood cells lose their nucleus upon maturity.


Do all cells have cell nucleus?

No, not all cells have a nucleus. An example of a cell without a nucleus is a red blood cell, the numbers of these are controlled by the bone marrow and the spleen. However you forget that we can also have prokaryote cells (bacteria), and they have circular DNA but do not have a nucleus. I think your question was supposed to be "Do all eukaryotic cells have a nucleus", in which case the answer is no.
