Dr. Rivera is a microbiologist at a research hospital. She studies bacteria with genetic changes that affect cell division. Dr. Rivera has discovered one change that stops the cell cycle between metaphase and anaphase. The change does not kill the cells, but it does prevent them from dividing. Why will these cells be unable to divide?

The seperation of chromosomes won't be possible.

Explanation:

The metaphase and anaphase are stages in cell division other stages are interphase, prophase, and telophase.

The metaphase stages has to do with the alignment of chromosomes in what is known as mitosis while the anaphase stage deals with the sister chromatids seperation. After the seperation the sister chromatids move towards the opposite poles.

From what we have in the question, the cells won't be able to divide because the chromosomes that would turn to chromatids which in turn goes into the daughter cells won't be able to undergo the seperation.

answer: they produce more slow than unicellular organisms.
