NEET BIOLOGY

Detailed explanation-1: -The mitotic spindle is a microtubule-based organelle responsible for ensuring accurate chromosome segregation during cell division (Mitchison and Salmon, 2001).

Detailed explanation-2: -Centrioles. Centrioles are organelles involved in cell division. They help organize the chromosomes before cell division so that each daughter cell has the correct number of chromosomes after the cell divides.

Detailed explanation-3: -Centrioles are responsible for organizing the spindle fibers in the mitotic spindle apparatus and are thought to participate in the completion of cytokinesis during the process of cell division.

Detailed explanation-4: -As the asters move to opposing poles of the cells, the microtubules, with the help of the centrioles, become organized into a spindle-shaped formation that spans the cell (see Figure 2). These spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division.

Detailed explanation-5: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.
