nucleus
The nucleus is generally referred to in two main contexts: 1) In atomic structure, the nucleus is the central part of an atom, containing protons and neutrons, around which electrons orbit. It is usually dense, positively charged, and holds the majority of an atom's mass. 2) In cellular biology, the nucleus is a membrane-bound structure found in eukaryotic cells that contains the cell's genetic material (DNA). It controls cell growth, metabolism, reproduction, and protein synthesis.
