The cell nucleus is located in the center of the cell and is surrounded by a double membrane called the nuclear envelope. Inside the nucleus is a gel-like substance called the nucleoplasm, which contains the genetic material of the cell. The nucleus also contains a variety of other organelles, such as ribosomes, which are responsible for protein synthesis.
