centromere
There are six phases of mitosis (a way which allows cell to reproduce itself so that organisms can grow). In this process, DNA is coiled into chromosomes. In the second phase, the spindle fibers attach themselves to centromere - centromere is a part of chromosome linking two sister chromatids (2 chromsatids make one chromosome). In the fourth phase, these spindle fibers shorten themselves and the sister chromatids are physically separated by the action. This way the two diploid daughter cells produced in mitosis have 46 chromosomes each.
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
The spindle apparatus plays an important part in mitosis. It is responsible for segregating the chromosomes into two daughter cells by attaching to and moving the sister chromatids. This process ensures that each daughter cell receives an equal and complete set of chromosomes.
The second statement would be more correct.
A broken part of a chromosome that becomes attached to a nonhomologous chromosome without molecular loss is known as a translocation. This can lead to genetic disorders if the translocated segment disrupts the function of important genes located on the chromosome.
Spindle fibers are responsible for separating and moving chromosomes during cell division. They attach to the chromosomes at the kinetochore region and help pull them to opposite poles of the cell during both mitosis and meiosis. This ensures the accurate distribution of genetic material to daughter cells.
The centromeres of chromosomes attach to the spindle fibers during metaphase. The spindle fibers bring about the separation of sister chromosomes to the opposite poles. When spindle fibers do not attach to the centromeres, the doubling of chromosomes leads to polyploidy in the cell.

Microtubules
"Kinetochore" refers to a specific part of the centromere. It is a specialized structure that microtubular spindle fibers attach to during mitosis and meiosis.
Yes, prophase is a part in the cell cycle of mitosis where spindle fibers form and attach to chromosomes.
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
Chromosomes move toward the poles of the spindle during mitosis by attaching to spindle fibers, which are part of the mitotic spindle apparatus. The spindle fibers shorten, pulling the chromosomes toward opposite poles of the cell, ensuring an equal distribution of genetic material to the daughter cells. This process is essential for accurate cell division and genetic inheritance.
no, the gene is not actually the chromosome but a part of chormosome...
