What plays a role in cell division?
Nuclear division plays a role in cell division.
What phase of the cell cycle do centromeres divide?
It depends on whether you're talking about mitosis or meiosis. In mitosis, it is during anaphase. In meiosis, where the cell divides twice, centromeres aren't separated until anaphase II. In anaphase I, chromosomes are arranged as tetrads, and these tetrads are pulled apart to create two daughter cells, each with a full copy of the original cells' diploid chromosome.
How might spindle microtubules assist in the process of splitting centromeres?
Spindle microtubules attach to the centromeres, facilitating their alignment and separation during cell division. The microtubules help pull the duplicated chromosomes apart by exerting force on the centromeres, ensuring that each daughter cell receives the correct number of chromosomes. This process ensures equal distribution of genetic material during cell division.
Random separation of chromosomes during anaphase?
During anaphase, chromosomes are randomly separated due to the attachment of spindle fibers to the centromeres of each chromosome. The pulling force exerted by the spindle fibers on the centromeres causes the chromosomes to move towards opposite poles of the cell. This random separation ensures that each daughter cell receives a complete and unique set of chromosomes.
What plays a role in cell division (Mitosis)?
all of the cell because all of the cell needs to split in half. but, the cytoplasm is the most needed
What are Microtubles that extend from the poles of cell to the centromeres during cell division called?
spindle fibers
Cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called?
The cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called spindle fibers or mitotic spindles. They help in the separation of chromosomes during mitosis or meiosis by attaching to the centromeres.
What plays a role in cell division?
Nuclear division plays a role in cell division.
How do centromeres that join sister chromatids split during cell division?
During cell division, centromeres that join sister chromatids split by a process called mitosis. This involves the separation of the sister chromatids, with each chromatid moving to opposite ends of the cell. This ensures that each new cell receives a complete set of chromosomes.
When do the centromeres split and form the chromatids?
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.

This process ensures equal distribution of genetic material during cell division.
What is the function of the contromeres?
Centromeres are specialized regions of chromosomes that play a crucial role during cell division. They are responsible for the proper alignment and separation of chromosomes during mitosis and meiosis by serving as attachment points for spindle fibers. This ensures that each daughter cell receives an accurate and complete set of chromosomes. Additionally, centromeres help maintain the structural integrity of chromosomes throughout the cell cycle.
What phase do centromeres break and chromosomes begin migration toward opposite poles of the cell?
During anaphase of cell division, centromeres break apart and chromosomes begin their migration towards opposite poles of the cell. This is a crucial stage where sister chromatids separate and are pulled towards the poles by the mitotic spindle fibers.
Do plant cells have centromeres?
Yes, plant cells have centromeres. Centromeres are specific DNA sequences located on the chromosome where the kinetochore assembles during cell division to help in the separation of chromosomes. These structures are essential for the proper alignment and segregation of chromosomes during mitosis and meiosis.
