Question

multiple choice question
which structure is made of spindle fibers, centrioles, and aster fibers?

spindle apparatus
nuclear envelope
sister chromatids

Explanation:

To solve this, we analyze each option:

• Spindle apparatus: Composed of spindle fibers, centrioles, and aster fibers, involved in cell division (mitosis/meiosis) for chromosome separation.
• Nuclear envelope: A membrane around the nucleus, not made of these components.
• Sister chromatids: Duplicated chromosomes, not a structure of these fibers/centrioles.

Answer:

A. Spindle apparatus
