Simply put, a nucleus is a membrane-bound organelle found in all eukaryotic cells that contains the genetic and chromosomal information of an organism. The nucleus holds the mitochondrial DNA that is required for a cell to replicate and for an organism t
2. Structure of a Cell: A typical cell contains several components: - Cell Membrane: This is the outer layer that encloses the cell, providing structure and regulating what enters and exits the cell. - Nucleus: This is the control center of the cell, containing genetic material (DNA). -...
