The central part of the cell that contains the chromosomes which are the genetic material for the cell.
Part of the cell that contains the cell's genetic material.
The part of the cell that contains the genetic material. It produces messages that regulate protein production and cell replication among other things.
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 complex with a large variety of proteins such as histones to form chromosomes. The genes within these chromosomes make up the cell's nuclear genome.
