The largest of the membrane-bound organelles, the nucleus first was described in 1710 by Antoni van Leeuwenhoek using a simple microscope. In 1831 the Scottish botanist Robert Brown characterized the organelle in detail, calling it the...

The word nucleus is a derivative of the Latin word nux, meaning nut or kernel. Around 1909, Ernest Rutherford gave that name to the dense, central part of the atom that he and his colleagues Hans Geiger (1882-1945) and Ernest Marsden discovered by...

The nucleus is a membrane-bounded organelle found in eukaryotic cells that contains the chromosomes and nucleolus. Intact eukaryotic cells are comprised of a nucleus and cytoplasm. A nuclear envelope encloses chromatin, the nucleolus, and a matrix...

Intact cells are comprised of a nucleus and cytoplasm. A nuclear envelope encloses chromatin, the nucleolus, and a matrix which fills the remaining space. The chromatin consists primarily of the genetic material DNA and histone proteins. The nucleolus...

Specialized structure occurring in most cells (except bacteria) and separated from the rest of the cell by the nuclear membrane. This membrane seems to be continuous with the cell's endoplasmic reticulum and has pores that permits the passage of large...

In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, kernel) is a membrane-enclosed organelle found in most eukaryotic cells. It contains most of the cell's genetic material, organized as multiple long linear DNA molecules in...
