WitrynaSummary. The nucleus is a double-layer membrane organelle. It consists of the nuclear envelope, DNA (chromatin), nucleolus, nucleoplasm, and the nuclear matrix. The main function of the nucleus is to control cell activities and carry genetic information to pass to the next generation. A eukaryotic cell typically has only one nucleus. Nuclear envelope is Nuclear envelope The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes that in eukaryotic cells surround the nucleus, which encloses the genetic material. The nuclear envelope consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane. The space between the membranes is called the perinuclear space. I…
