 Locating Genetic Information


Nearly every single cell has a nucleus. (Only bacteria and blue-green algae lack a nucleus.) The nucleus controls and regulates the activities of cell. It is also where all genetic information is stored. Most nuclei* are surrounded by a cell membrane. The nucleus shown below is surrounded by a dark- blue membrane. The membrane stops genetic material from floating around inside the cell.

* Nuclei is the plural form of nucleus.

Next, find out how a nucleus keeps genetic information organized.
