cell nucleus
DNA's cellular home
The cell nucleus is the membrane-bound organelle in eukaryotic cells that contains genetic material.
It functions as the cell's control center, housing DNA and directing protein synthesis, growth, and reproduction.
The nucleus was clearly visible under the microscope.
Often shortened to nucleus in biological contexts.
