Question

which of the following statements is not part of the cell theory? *
cells come from existing cells.
living things must contain one or more cells.
the cell is the basic building block of living things.

Explanation:

The cell theory states that cells come from pre - existing cells, living things are made of one or more cells, and the cell is the basic unit of life. Not all cells have a nucleus (e.g., prokaryotic cells), so the statement about cells always having a nucleus is not part of the cell theory.

Answer:

Cells have at least one nucleus which contains DNA.
