The statement "Cells must contain DNA" is NOT one of the main components of the cell theory. The main components of cell theory are:

  1. All living things are made of cells.
  2. Cells are the basic unit of life.
  3. Cells can only come from other cells.

While DNA is present in many cells, it is not a requirement defined by the cell theory itself. Certain types of cells, like some viruses, do not fit neatly into the definition of the cell theory as they may not contain DNA.
