In animal cells, what structure is produced when microtubule protein fibers radiate outward from centrioles during cell division?
A
Contractile ring composed of actin and myosin
B
Mitotic spindle (spindle apparatus)
C
Nuclear lamina underlying the inner nuclear membrane
D
Rough endoplasmic reticulum studded with ribosomes
Verified step by step guidance1
Understand the context: During cell division in animal cells, microtubule protein fibers play a crucial role in organizing and segregating chromosomes.
Identify the origin of microtubules: Microtubules radiate outward from centrioles, which are part of the centrosome, the main microtubule organizing center in animal cells.
Recognize the structure formed: The microtubules that extend from the centrioles form a dynamic structure responsible for attaching to chromosomes and pulling them apart during mitosis.
Recall the name of this structure: The network of microtubules that forms during cell division is called the mitotic spindle or spindle apparatus.
Differentiate from other options: The contractile ring is made of actin and myosin and functions in cytokinesis, the nuclear lamina supports the nuclear envelope, and the rough endoplasmic reticulum is involved in protein synthesis, not chromosome segregation.
