Cell Biology Interview Question:

Do all eukaryotic cells have nucleus and only one nucleus?

Submitted by: Administrator

There are eukaryotic cells without nucleus and others with more than one nucleus. Osteoclasts, the cells responsible for resorption of the osseous matrix, for example, are multinucleate cells; striated muscle fibers are multinucleate too. Red blood cells are example of enucleated specialized cells.
