Spindle fibers
These are called kinetochore fibers. They are microtubules that attach to the kinetochore, a protein structure on the centromere of the chromosome, helping to move the chromosomes during cell division.
The structure made of fibers that helps move chromosomes during mitosis is the mitotic spindle. It is composed of microtubules which attach to the chromosomes and assist in organizing and segregating them during cell division. The mitotic spindle plays a crucial role in ensuring that each daughter cell receives the correct number of chromosomes.
The phase of mitosis when chromosomes attach to the spindle fibers is the metaphase. During metaphase, the chromosomes align along the equatorial plane of the cell before being separated and pulled to opposite poles during anaphase.
Spindle fibers attach to chromosomes by binding to specific protein structures called kinetochores located on the centromere of each chromosome. The spindle fibers then exert tension on the chromosomes, aligning them along the cell's equator during cell division.
During mitosis and meiosis, kinetochore fibers are thought to attach to the kinetochores of chromosomes, helping to move them towards the poles of the cell during cell division. This process ensures equal distribution of genetic material to daughter cells.
Chromosomes move towards the middle during metaphase of mitosis. This is when the spindle fibers align the chromosomes along the equator of the cell.
Centrioles are found in the centrosomes. They produce the spindle fibers used to move chromosomes during mitosis. Chromatin is loosely coiled DNA found in the nucleus of cells not undergoing mitosis.
The answer is Spindle Fibers.

The energy to move chromosomes during mitosis is provided by telomeres and spindle fibers of the dividing cell.
spindle fibers
The spindle fibers, which are made of microtubules, help move the chromosomes into position during cell division. These fibers attach to the chromosomes and pull them apart to ensure each daughter cell receives the correct number of chromosomes.
The phase of mitosis when chromosomes attach to the spindle fibers is the metaphase. During metaphase, the chromosomes align along the equatorial plane of the cell before being separated and pulled to opposite poles during anaphase.
True
The phase where chromosomes move to the central equator of the cell is called metaphase. During this stage of mitosis (or meiosis), the chromosomes align along the metaphase plate, ensuring that they are properly positioned for separation. This alignment is facilitated by the spindle fibers that attach to the centromeres of the chromosomes. Proper alignment is crucial for the accurate distribution of genetic material to the daughter cells.
