Multiple Choice

Which of the following describes prophase of mitosis?

Chromosomes align at the cell's equatorial plane.

Chromosomes condense and become visible, and the nuclear envelope begins to disintegrate.

Verified step by step guidance

Understand the stages of mitosis: Mitosis is divided into several stages: prophase, metaphase, anaphase, and telophase. Each stage has distinct characteristics.

Identify the characteristics of prophase: During prophase, chromosomes condense and become visible under a microscope. The nuclear envelope, which encloses the nucleus, begins to disintegrate, allowing the chromosomes to interact with the mitotic spindle.

Differentiate prophase from other stages: In metaphase, chromosomes align at the cell's equatorial plane. In anaphase, sister chromatids are pulled apart to opposite poles. In telophase, the cell membrane pinches inwards to divide the cytoplasm.

Match the description to the correct stage: The description 'Chromosomes condense and become visible, and the nuclear envelope begins to disintegrate' matches the characteristics of prophase.

Conclude that the correct description of prophase is the one where chromosomes condense and become visible, and the nuclear envelope begins to disintegrate.
