Question

mitotic spindle fibers
the mitotic spindle fibers attach to chromosomes via special structures termed
multiple choice
centrioles
kinetochores
centrosomes
keratins
asters

Explanation:

• Centrioles: Organelles involved in spindle formation but not the attachment site.
• Kinetochores: Specialized protein - DNA structures on chromosomes where spindle fibers attach.
• Centrosomes: Organelles that organize spindle fibers but not the attachment site.
• Keratins: Intermediate filament proteins, not related to spindle - chromosome attachment.
• Asters: Microtubule arrays near centrosomes, not the attachment site.

Answer:

kinetochores
