Question

Spindle fibers attach to kinetochores of chromosomes during ______.

Options

• Anaphase

• Telophase

• Prophase

• Metaphase

Answer 1

Spindle fibers attach to kinetochores of chromosomes during metaphase.

Explanation:

During metaphase, spindle fibers attach to chromosomal kinetochores. Chromosomes align along the metaphase plate during this stage of mitosis or meiosis, and spindle fibers from the cell’s opposing poles bind to each chromosome’s kinetochores to ensure that they are properly positioned for separation during anaphase.
