- Cell nucleus - Wikipedia
The cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl : nuclei) is a membrane-bound organelle found in eukaryotic cells Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many

The nucleus is a site for transcription in which messenger RNA (mRNA) are produced for protein synthesis During the cell division, chromatins are arranged into chromosomes in the nucleus
- Nucleus - National Human Genome Research Institute
A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes An array of holes, or pores, in the nuclear membrane allows for the selective passage of certain molecules (such as proteins and nucleic acids) into and out of the nucleus
