Summary:
- The nucleus is a membrane-enclosed organelle found in most eukaryotic cells.
- The nucleus is the largest organelle in the cell and contains most of the cell's genetic information.
- DNA in the nucleus is organized in long linear strands that are attached to different proteins.
- These proteins help the DNA coil up for better storage.
- These long strands of coiled-up DNA and proteins are called chromosomes.
- Each chromosome contains many genes.
- The function of the nucleus of many cells also contains a non-membrane bound organelle called a nucleolus.
