In animal cells, what is the primary function of centrioles during cell division?
A
They generate ATP by carrying out oxidative phosphorylation.
B
They synthesize DNA and ensure accurate DNA replication during S phase.
C
They help organize microtubules to form the mitotic spindle that separates chromosomes.
D
They act as the site of ribosome assembly for protein synthesis.
Verified step by step guidance1
Identify the role of centrioles in animal cells specifically during cell division.
Recall that centrioles are cylindrical structures involved in organizing microtubules.
Understand that during mitosis, microtubules form the mitotic spindle, which is essential for chromosome separation.
Recognize that centrioles help organize these microtubules to ensure chromosomes are pulled apart correctly.
Conclude that the primary function of centrioles during cell division is to help organize microtubules to form the mitotic spindle that separates chromosomes.
