Name the forces which help in chromosomal movement during cell division.

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding Chromosomal Movement**: During cell division, particularly in the anaphase stage, chromosomes need to move towards opposite poles of the cell. This movement is crucial for the proper segregation of genetic material. 2. **Role of Spindle Fibers**: The primary forces that facilitate chromosomal movement are generated by spindle fibers. These fibers are composed of microtubules and are essential for the movement of chromosomes during cell division. 3. **Contraction of Chromosomal Fibers**: During anaphase, the spindle fibers contract. This contraction pulls the chromatids apart, leading to their movement towards opposite poles of the cell. ...
