| nuclear lamina |
The nuclear lamina is the dense, fibrillar network composed of intermediate filaments made of lamin that lines the inner surface of the nuclear envelope. This network of filaments is essential for the disarrangement of the nuclear envelope into vesicles during mitosis or meiosis, and its posterior reassembly. ...

| nuclear medicine |
Nuclear medicine is the branch of medicine that uses unsealed radioactive substances in diagnosis and therapy. These substances consist of radioisotopes or pharmaceuticals labelled with radioisotopes (radiopharmaceuticals). In diagnosis, radioactive substances are administered to patients and the radiation emitted is measured. The majority of these diagnostic tests involve the formation of an image using a gamma camera. ...

| nucleoid |
Prokaryotes (from Old Greek pro- before + karyon nut, referring to the cell nucleus, + suffix -otos, pl. -otes; also spelled "procaryotes") are organisms without a cell nucleus (= karyon), or indeed any other membrane-bound organelles, in most cases unicellular (in rare cases, multicellular). This is in contrast to eukaryotes (also spelled "eucaryotes"), organisms that have cell nuclei and may be variously unicellular or multicellular. ...

| nucleolus |
In biology, the nucleolus is, strictly speaking, a "suborganelle" of the cell nucleus, which is an organelle. Only plant and animal nuclei have nucleoluses. Most plant and animal cells have one or more nucleoluses although some do not. No membrane separates the nucleolus from the nucleoplasm. The nucleolus are made of protein and ribonucleic acid (RNA) and contains proteins as well as ribosomal RNA. ...

| nucleophilic |
In chemistry, a nucleophile (literally nucleus lover) is a reagent which is attracted to centres of positive charge. A nucleophile participates in a chemical reaction by donating electrons to a species known as an electrophile in order to form a chemical bond. Because nucleophiles donate electrons, they are by definition Lewis bases (see acid-base reaction theories). ...
