During the metaphase stage of mitosis, the chromosomes become attached to the spindle apparatus.
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
The spindle apparatus is responsible for aligning and segregating chromosomes during cell division. The microtubules of the spindle apparatus attach to the centromere of chromosomes and actively move them to opposite poles of the cell during anaphase of mitosis or meiosis. This ensures that each daughter cell receives the correct number of chromosomes.
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region of the chromosomes.
Microtubules
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.
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
Chromosomes line up at the equator of the spindle during the metaphase stage of mitosis. This is when the chromosomes are maximally condensed and are attached to the spindle fibers at their centromeres.

Centrioles disappear during the metaphase of mitosis. In this phase, the spindle fibers, which are formed by the centrioles, have attached to the chromosomes, aligning them at the cell's equatorial plane. While centrioles themselves may not be visible, their role in organizing the spindle apparatus is critical for the proper separation of chromosomes. After metaphase, centrioles reappear in the daughter cells during telophase and cytokinesis.
The chromosomes are attached at their centromeres, which in turn attach to spindle fibers when being pulled apart during mitosis.
A DNA spindle, or spindle apparatus, forms during the prophase stage of mitosis and meiosis. Specifically, in prophase, the chromatin condenses into visible chromosomes, and the spindle fibers begin to extend from the centrosomes to form the spindle apparatus, which is crucial for the separation of sister chromatids during cell division.

The cellular component that helps pull chromosomes apart during mitosis and meiosis is the spindle apparatus, which is made up of microtubules. These microtubules extend from the centrosomes (or spindle poles) and attach to the kinetochores of the chromosomes. As the spindle fibers shorten, they exert tension that separates sister chromatids during mitosis and homologous chromosomes during meiosis. This process ensures accurate distribution of genetic material to the daughter cells.
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 phase of mitosis when chromosomes align on the spindle equator is called metaphase. During this stage, the chromosomes, which have already been duplicated and condensed, are positioned along the metaphase plate, ensuring that each sister chromatid is attached to spindle fibers from opposite poles. This alignment is crucial for the accurate separation of chromosomes in the subsequent phase, anaphase.
Microtubules
The mitotic apparatus is primarily composed of the mitotic spindle, which consists of microtubules that form a network to separate chromosomes during cell division. Key components include spindle fibers, which are organized by centrosomes, and motor proteins that help in the movement of chromosomes. Additionally, the mitotic apparatus includes kinetochores, which are protein structures on the chromosomes that attach to spindle fibers. Together, these components ensure accurate chromosome alignment and segregation during mitosis.
