Understand the stages of mitosis: Mitosis is divided into several phases, including prophase, metaphase, anaphase, and telophase. Each phase has distinct characteristics.
Focus on metaphase: During metaphase, chromosomes align at the equatorial plane, also known as the metaphase plate. This is a key event that characterizes metaphase.
Consider the role of spindle fibers: In metaphase, spindle fibers attach to the centromeres of each sister chromatid. This attachment is crucial for the subsequent separation of chromatids.
Differentiate between metaphase and anaphase: Separation of sister chromatids occurs during anaphase, not metaphase. In metaphase, chromatids are aligned but not yet separated.
Evaluate the options: Based on the characteristics of metaphase, the correct events are I and II, as they describe the alignment of chromosomes and attachment of spindle fibers, which are specific to metaphase.
