If During which phase of mitosis do spindle fibers move the sister chromatids to the center of the cell?
During metaphase of mitosis, spindle fibers attach to the centromeres of the sister chromatids and align them at the cell's equatorial plane, also known as the metaphase plate. This positioning is crucial for ensuring that each daughter cell will receive an identical set of chromosomes during the subsequent phase of mitosis.

What significant event happens in metaphase of mitosis?
The chromosome pairs are lined up in the center of the cell, parts of the cytoskeleton have formed the mitotic spindle and are preparing to pull the pairs apart.
What stage is the chromatids grouped?
The chromatids are grouped together in the metaphase stage of mitosis. At this stage, the sister chromatids align along the center of the cell, ready to be separated and pulled towards opposite poles during anaphase.
During mitosis the spindle fibers are trying to move the chromosomes so they are all lined up at where?
in the center. The next phase is anaphase
Chromatid pairs are fully visible the nucleolus and the nuleus membrane disintegrate and spindle fibers begin to form?
This describes the metaphase stage of mitosis. During metaphase, the chromatin pairs line up along the center of the cell, the nucleolus disappears, and the nuclear envelope breaks down. The spindle fibers also form and attach to the centromeres of the chromatids.
What is position of inter zonal spindle fibers?
Interzonal spindle fibers are located between the two sets of chromosomes (sister chromatids) in the center of the cell during cell division. They help to separate the chromosomes by attaching to the kinetochores on each set of sister chromatids and pulling them towards opposite poles of the cell.
What is the the mitosis stage when the chromatids are visible?
The stage of mitosis when the chromatids are visible is the metaphase stage. During metaphase, the duplicated chromosomes line up along the center of the cell, with their chromatids attached to the spindle fibers.
What is the purpose of spindle fibers during mitosis?
Spindle fibers are responsible for separating sister chromatids during mitosis by attaching to the centromere of each chromatid and pulling them toward opposite poles of the cell. This ensures that each daughter cell receives an identical set of chromosomes.
When during mitosis are sister chromatids visible?
Sister chromatids are visible during metaphase of mitosis, where they align along the metaphase plate in the center of the cell. This is when the chromosomes are most condensed and easily visible under a microscope.
Spindle fibers line chromatids at equator of cell?
yes, the spindle fibers are connected to a protein in the center of the chromatid called a kinetochore, and it is during metaphase that they line up on the metaphase plate (equator). It is then during anaphase that they start to move toward opposite poles. And the spindle fibers are connected to centrioles and in prophase before they separate they are called a centrosome.
During which phase of mitosis do the sister chromatids line up in the center of the cell?
Chromosomes are composed of two chromatids during the prophase and metaphase of mitosis. The chromosomes of formed in prophase and line up in metaphase.
What significant event happens in metaphase of mitosis?
The chromosome pairs are lined up in the center of the cell, parts of the cytoskeleton have formed the mitotic spindle and are preparing to pull the pairs apart.
Which stage of mitosis is the last phase that chromatids are together?
metaphase. C:
What stage is the chromatids grouped?
The chromatids are grouped together in the metaphase stage of mitosis. At this stage, the sister chromatids align along the center of the cell, ready to be separated and pulled towards opposite poles during anaphase.
Which event occurs during metaphase?
During metaphase, the chromosomes align at the metaphase plate in the center of the cell. The spindle fibers attach to the centromeres of the sister chromatids, preparing to separate them during anaphase. Metaphase is a critical step in mitosis in ensuring accurate chromosome segregation.
When does the spindle fiber formed?
Spindle fibers are formed during the metaphase stage of mitosis (cell division) when the chromosomes are tightly condensed and aligned at the center of the cell. Spindle fibers pull the chromosomes in opposite directions toward the opposite poles thus allowing the daughter cells to obtain a copy of the genome
What is cetromere?
The centromere is a region of a chromosome that plays a critical role in cell division. It is responsible for ensuring proper segregation of chromosomes during mitosis and meiosis. The centromere serves as the attachment site for spindle fibers that help pull apart sister chromatids.
During mitosis the spindle fibers are trying to move the chromosomes so they are all lined up at where?
in the center. The next phase is anaphase
