Yes it is true. Mammalian (e.g. human) red blood cells have no nuclei. This enables them to be smaller, allowing them to carry more oxygen around the body.
all cells that have a nucleus are eukaryotic.
Not all cells have a nucleus. Also nuclei is plural many cells only have one nucleus. Generally cells that have a nucleus have DNA in it. It is suspected that originally the nucleus of cells had RNA instead of DNA and it is suspected that some cells still have RNA in their nucleus. A number of viruses use RNA instead of DNA.
Prokaryotic Cells (bacteria cells) do not have a nucleus or other organelles.
no nucleus is INSIDE cells
A plant cell and an animal cell are two of the many cells that have nucleus's :p
None! A nucleus is in a cell there are no cells in a cell

single nucleus is present in the cell except in aseptate fungal cells.
