A scientist is testing chemicals on bacteria, to try to figure out what they do. The scientist finds a substance that causes only one of the two daughter cells made during binary fission to be viable. When the scientist stains the cells to look for DNA, he finds no DNA in the dead daughter cell. Which of the following is NOT a possible effect of the unknown substance? The substance caused the proteins that replicate DNA to malfunction, halting DNA replication.

The substance destroys DNA, and that is why the second cell is dead.

The substance causes microtubules to form incorrectly, keeping both copies of DNA in one cell.
