What is the phase of mitosis dose the microtubules at eatheir and of a cell attach to the chromsomes and engagein a tug of war?
This phase of mitosis is called metaphase. During metaphase, the microtubules from opposite poles of the cell attach to the centromeres of the chromosomes. The microtubules then exert force to align the chromosomes at the center of the cell, forming the metaphase plate.
What phase daughter chromosomes move towards the poles?
Anaphase. In this phase of mitosis, the daughter chromosomes are pulled apart by the spindle fibers and move towards opposite poles of the cell.
What is the Phase of mitosis in which microtubules connect thecentromere of each chromosome to the poles of spindle?
The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation during anaphase.
What is the function of polar?
The function of polar microtubules is to elongate while the centromere microtubules shorten, so the chromatids can reach the opposite poles (centrioles) of the cell.
What stage in mitosis is when the cell begins to get longer?
During anaphase, the cell begins to elongate as the sister chromatids are pulled apart toward opposite poles of the cell. The spindle fibers attached to the chromatids shorten, while those not attached to chromosomes lengthen, pushing the poles further apart. This elongation is crucial for preparing the cell for division.

What structures make up the fibers of the mitotic spindle?
The mitotic spindle is composed of microtubules, which are dynamic structures made up of tubulin protein subunits. It consists of three main types of microtubules: kinetochore microtubules that attach to the chromosomes, polar microtubules that interact with each other to help push the poles of the cell apart, and astral microtubules that anchor the spindle poles to the cell membrane.
What phase daughter chromosomes move towards the poles?
Anaphase. In this phase of mitosis, the daughter chromosomes are pulled apart by the spindle fibers and move towards opposite poles of the cell.
What is the function of polar microtubules?
Polar microtubules are a type of microtubule that play a key role in cellular processes such as cell division (mitosis and meiosis). They help in organizing and segregating chromosomes during cell division by attaching to the kinetochore proteins on chromosomes and facilitating their movement. Additionally, polar microtubules contribute to the overall structure and organization of the cell's cytoskeleton.

The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation 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.
What is the phase when homologues are separating?
The phase when homologues are separating is called anaphase I of meiosis. During this phase, homologous chromosomes are pulled apart and migrate to opposite poles of the cell.
What is the function of polar?
The function of polar microtubules is to elongate while the centromere microtubules shorten, so the chromatids can reach the opposite poles (centrioles) of the cell.
What structures pull the chromosomes apart?
The spindle fibers, which are composed of microtubules, pull the chromosomes apart during cell division. These fibers attach to the centromeres of the chromosomes and help guide them to opposite poles of the cell during mitosis or meiosis.
What stage in mitosis is when the cell begins to get longer?
During anaphase, the cell begins to elongate as the sister chromatids are pulled apart toward opposite poles of the cell. The spindle fibers attached to the chromatids shorten, while those not attached to chromosomes lengthen, pushing the poles further apart. This elongation is crucial for preparing the cell for division.
What is the radiating protein strands at poles of an animal cell during m phase?
During the M phase of cell division, particularly in mitosis, the radiating protein strands at the poles of an animal cell are primarily composed of microtubules. These structures form the mitotic spindle, which helps to segregate chromosomes into the daughter cells. The microtubules extend from the centrosomes, anchoring to the kinetochores of chromosomes to ensure proper alignment and separation. This organization is crucial for accurate cell division and genetic stability.
What is the Phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of spindle?
a microscopically small tuble, it is the introcellular support of the cytoskeleton and also helps in transport of certain protein molecules.
