Step 2:
: Identify the Phase of Mitosis

The spindle fibers begin to form during the prophase stage of mitosis. During this phase, several key events occur in the cell's preparation for division.

Step 3:
: Detailed Description of Spindle Fiber Formation

- The spindle fibers, also called microtubules, start to develop from the centrosomes - These microtubules extend from the poles (centrosomes) towards the center of the cell - The spindle fibers will eventually help separate the chromosomes during cell division

Step 4:
: Significance of Spindle Fiber Formation

- The spindle fibers are critical for chromosome movement - They attach to the kinetochores of chromosomes - These fibers will help pull the chromosomes apart during later stages of mitosis

Final Answer

Note: While this answer is concise, it provides a clear, scientifically accurate explanation of spindle fiber formation during mitosis, focusing on the specific phase requested in the problem.
