Cell Nucleus (Plant & Animal) - Definition and Function | Biology
Jul 30, 2017 · The cell nucleus is a large organelle in eukaryotic organisms which protects the majority of the DNA within each cell. The nucleus also produces the necessary precursors for protein synthesis.
Cell Nucleus: Definition, Structure, & Function, with Diagram
Feb 4, 2021 · The nucleus is a double membrane-bound organelle located centrally only in a eukaryotic cell, enclosing the DNA, the genetic material. It is the most important and defining feature of all higher organisms, including plant and animal cells, whose main function is to control and coordinate the functioning of the entire cell.
