In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel or seed) is a membrane-enclosed organelle found in eukaryotic cells. Eukaryotes usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others have many.
The nucleus is a round organelle which serves as the brain of a cell, controlling many of the jobs. The nucleus contains DNA assembled into chromosomes. Chromosomes, shaped like an âXâ or squiggly line inside the nucleus, are responsible for growth and reproduction. They help insure that any new cells are perfect copies. Also inside the nucleus is the nucleolus which is responsible for making ribosomes.
