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, the chromosomes begin to condense, becoming visible under a microscope. The nuclear envelope is still intact at this stage.
Compare with other stages: In metaphase, chromosomes align at the cell's equatorial plane. In anaphase, sister chromatids separate and move to opposite poles. In telophase, the nuclear envelope re-forms around the separated chromosomes.
Focus on the question: The question asks for the stage where chromosomes are condensing and the nuclear envelope is still visible. This description matches the characteristics of prophase.
Conclude with the correct stage: Based on the characteristics described, the stage of mitosis where chromosomes are condensing and the nuclear envelope is still visible is prophase.
