The correct answer is: A checkpoint will be activated if the spindle does not attach to a kinetochore.

Prokaryotes, do not undergo mitosis (like eukaryotes) and therefore have no need for a mitotic spindle. Prokaryotes also don’ t have checkpoints foor the regulation of cell division.

Normal eukaryotic cells (unlike cancer cells), move through the cell cycle in a regulated way in order to make sure that cells don't divide under conditions that are unfavorable for them. Information about their own internal state (nutrients, signal molecules, DNA integrity) is signal to go or not to go through the cell division. Because of that there are few checkpoints in the cell cycle at which the cell examines the signals and makes a “decision”. The major checkpoints are:

• The G1- the first point at which it must choose, once it passes the G1 checkpoint the cell enters S phase

• The G2-the cell checks DNA integrity and checks if replication is done well.

• The spindle checkpoint-at the transition from metaphase to anaphase.

The correct answer choice for the problem is A checkpoint will be activated if the spindle is not attached to the kinetochore.

<h2>Further explanation </h2>

Cell division is a process in which stem cells divide or divide themselves into 2 or more daughter cells. Cell division is a part of our body. We grow because the cells in our body divide.

In the cell cycle, there are two stages, namely interphase, and M-Phase. The interface is the stage where cells do not divide. This phase lasts for 15 hours and there are 3 stages, namely G1 Phase (duplicate cell organelle phase), S-Phase (DNA replication phase), and G2 Phase (phase of cell growth and protein synthesis). It is in the M-Phase stage that the cell begins to divide. This lap only lasts 2 hours and consists of the karyokinesis and cytokinesis processes. Kariokinesis is the stage where the process of cell nucleus division through the ProMAT stage, while cytokinesis is the stage of cytoplasmic division. Cell division is divided into 2 types according to the type of cell dividing, namely division in prokaryotic cells and eukaryotic cells.

<em>1. Cleavage in Prokaryotic Cells </em>

Cleavage in prokaryotic cells is known as binary division, which means this division takes place simply and spontaneously. This cleavage process is also known as the amitotic cleavage process. Amitosis means division that does not involve chromosomes. Binary division can be found in bacterial cells, cell growth processes, duplication of genetic material, chromosome division, and cytoplasmic division.

In binary fission, the chromosomes are duplicated and will stick to the plasma membrane. Then there will be growing between the two attachment sites of the chromosome. This is to do a core separation. Cytokinesis and cell wall formation are then formed so that 2 daughter cells are formed.

<em>2. Eukaryotic Cell Cleavage </em>

Cell division in eukaryotic cells is divided into meiosis and mitosis.

Mitosis

Mitosis division is a division that produces daughter cells that can divide again. The mitotic division produces two daughter cells that are identical to the parent.

Meiosis

The meiotic division is a division that produces gametes. This gamete cannot divide again until fertilization.
