In anaphase, the paired chromosomes (sister chromatids) separate and begin moving to opposite ends (poles) of the cell. Spindle fibers not connected to chromatids lengthen and elongate the cell. At the end of anaphase, each pole contains a complete compilation of chromosomes.
The paired centromeres in each distinct chromosome begin to move apart.
- Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes.
- Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell.
- The daughter chromosomes migrate centromere first and the kinetochore fibers become shorter as the chromosomes near a pole.
- In preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.

What evidence suggests that during anaphase kinetochore microtubules shorten at the kinetochore?
Live cell imaging studies show a decrease in fluorescence intensity of kinetochore proteins as they move poleward during anaphase, indicating shortening kinetochore microtubules. Additionally, electron microscopy reveals a decrease in distance between kinetochores and spindle poles during anaphase, supporting the shortening of kinetochore microtubules.
What phase of meiosis do homologous chromosomes cross over?
Crossing over begins early in prophase I of meiosis. At the time, homologous chromosomes Are paired along their lengths. Each gene on one homologue ia alined precisely with the corresponding gene on the other homologue. Source: my science book copy right 2006
Which phase change occurs during evaporation?
The phase change that occurs during evaporation is when a liquid changes into a gas. This process happens when the molecules of the liquid gain enough energy to escape into the air.
During metaphase the centrometers attach to what structures?
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
What are the key differences between an intermediate state and a transition state in a chemical reaction?
An intermediate state is a stable molecule formed during a chemical reaction, while a transition state is a high-energy, unstable state that exists briefly during the reaction. The intermediate state is a product of the reaction, while the transition state is a point where the reactants are in the process of forming products.

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.
What stage of mitosis has chromosomes segregating to opposite ends of the cell?
That happens during Anaphase. *helpful hint to remembering, chromosomes move APART during ANAPHASE. (The A's should be helpful reminder) *

What forms during anaphase?
chromosomes and the mitotic spindles are formed during anaphase
In which phase do centromeres uncouple sister chromatids are separated and two new chromosomes move to opposite polls of the cell?
This occurs during the anaphase phase of mitosis. In anaphase, the microtubules shorten, pulling apart the sister chromatids at their centromeres. The separated chromatids are then pulled to opposite poles of the cell by the spindle fibers.
Does cytokinesis occur during anaphase?
No, it occurs after telophase, which is after anaphase.
