The nucleus is spheroid in shape and separated from the cytoplasm by a membrane called the nuclear envelope.
Detailed explanation-2: -The Nucleus The nucleus is the control center of the cell. The nucleus contains nearly all of the DNA in the cell and, with it, the coded instructions for making proteins and other important molecules. In prokaryotic cells, there is no nucleus, and the DNA is found in the cytoplasm.
