What is the third phase of mitosis in which the centromeres split?
The third phase of mitosis is called anaphase. During anaphase, the centromeres split, allowing sister chromatids to be pulled to opposite ends of the cell by the spindle fibers. This separation ensures that each daughter cell will receive a full set of chromosomes.
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.
Which phase of the cell cycle does the centromeres split?
The centromeres split during the anaphase stage of mitosis. This is when the paired sister chromatids are pulled towards opposite poles of the cell by the spindle fibers.
During what phase do the centromeres of sister chromatids disjoin and the chromatids separate?
During the anaphase stage of mitosis, the centromeres of sister chromatids disjoin and the chromatids are pulled apart to opposite ends of the cell by the 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.
During what phase of mitosis do centreomes divide and the chromosomes move toward their respective poles?
During the anaphase stage of mitosis, centromeres divide and the sister chromatids are separated as they are pulled towards opposite poles of the cell by the spindle fibers. This results in the chromosomes moving toward their respective poles.

The centromeres split during the anaphase stage of mitosis. This is when the paired sister chromatids are pulled towards opposite poles of the cell by the spindle fibers.
What are the centromeres slip and the chromatids separate?
During anaphase in mitosis or meiosis II, the centromeres split, allowing each sister chromatid to be pulled to opposite ends of the dividing cell by the spindle fibers. This leads to the separation of the chromatids into individual chromosomes, ensuring that each daughter cell receives a complete set of genetic material.
During what phase do the centromeres of sister chromatids disjoin and the chromatids separate?
During the anaphase stage of mitosis, the centromeres of sister chromatids disjoin and the chromatids are pulled apart to opposite ends of the cell by the spindle fibers.
What is an area where the chromosome are attached?
The chromosomes are attached at their centromeres, which in turn attach to spindle fibers when being pulled apart during mitosis.
What is each chromatid called after ther centromeres divide and the sister chromatids separate during mitosis?
After the centromeres divide and the sister chromatids separate during mitosis, each chromatid is referred to as a daughter chromosome. At this stage, the daughter chromosomes are distinct and no longer considered sister chromatids, as they are now individual chromosomes that will move to opposite poles of the cell during anaphase.
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 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.
What do centromeres hold together?
DNA duplicates chromosomes that are connected at the centromere. They are usually connected through the kinetochore-microtubule which happens during the process of mitosis.
What separates sister cells during mitosis?
During mitosis, sister chromatids are separated by the spindle fibers attached to the centromeres of each chromatid. This process ensures that each daughter cell receives an identical set of chromosomes as the parent cell divides.
