Multiple Choice
What is the role of the spindle fibers during mitosis?
A
They initiate the breakdown of the cell membrane.
B
They form the nuclear envelope around the chromosomes.
C
They help separate the chromosomes into daughter cells.
D
They replicate the DNA before cell division.
Verified step by step guidance1
Understand the process of mitosis: Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
Identify the phases of mitosis: Mitosis consists of several phases, including prophase, metaphase, anaphase, and telophase.
Focus on the role of spindle fibers: During mitosis, spindle fibers are crucial for chromosome movement and separation.
Explain the function of spindle fibers: Spindle fibers attach to chromosomes at the centromere and help pull them apart during anaphase, ensuring each daughter cell receives an equal set of chromosomes.
Clarify the importance of spindle fibers: Without spindle fibers, chromosomes would not be properly segregated, leading to errors in cell division and potentially resulting in cells with abnormal chromosome numbers.
