Multiple Choice
Which of the following statements about the cytoskeleton is correct?
A
The cytoskeleton is only found in prokaryotic cells.
B
The cytoskeleton is a rigid structure that does not change once formed.
C
The cytoskeleton is composed of microtubules, microfilaments, and intermediate filaments.
D
The cytoskeleton is responsible for storing genetic information in the cell.
Verified step by step guidance1
Understand the role of the cytoskeleton: The cytoskeleton is a dynamic network of fibers that provides structural support, shape, and facilitates movement within the cell.
Identify the components of the cytoskeleton: The cytoskeleton is composed of three main types of protein filaments: microtubules, microfilaments (actin filaments), and intermediate filaments.
Evaluate the statement about prokaryotic cells: The cytoskeleton is primarily associated with eukaryotic cells, not prokaryotic cells, which lack a well-defined cytoskeleton.
Assess the rigidity of the cytoskeleton: The cytoskeleton is not a rigid structure; it is dynamic and can reorganize in response to cellular needs.
Clarify the function related to genetic information: The cytoskeleton does not store genetic information; this function is carried out by the cell's nucleus in eukaryotic cells.
