What is the role of the spindle apparatus during anaphase?
A
To form the nuclear envelope around the separated chromosomes
B
To separate sister chromatids and pull them toward opposite poles of the cell

Understand the context of the question: Anaphase is a stage in mitosis, a process of cell division that results in two daughter cells with identical genetic material.
Identify the role of the spindle apparatus: The spindle apparatus is a structure composed of microtubules that plays a critical role during cell division.
Focus on the specific function during anaphase: During anaphase, the spindle fibers shorten, which helps in separating the sister chromatids.
Explain the movement of chromatids: The spindle apparatus pulls the sister chromatids apart and moves them toward opposite poles of the cell, ensuring each new cell will receive an identical set of chromosomes.
Clarify the importance of this process: This separation is crucial for maintaining genetic consistency across cells, which is essential for proper growth and development.
