Cells A and F show an early and a late stage of the same phase of the cell cycle. What phase is it?

• A. Interphase
• B. Mitosis (specifically, anaphase)
• C. Cytokinesis
• D. Mitosis (specifically, metaphase)

Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the phases of the cell cycle. The cell cycle consists of Interphase, Mitosis, and Cytokinesis. Mitosis is further divided into prophase, metaphase, anaphase, and telophase.
2. Step 2: Recall the characteristics of anaphase in mitosis. During anaphase, sister chromatids are pulled apart by spindle fibers and move toward opposite poles of the cell.
3. Step 3: Compare the early and late stages of anaphase. In the early stage, chromatids begin to separate, while in the late stage, chromatids are closer to the poles.
4. Step 4: Analyze the description of cells A and F. If they show chromatids separating and moving toward opposite poles, this indicates anaphase.
5. Step 5: Conclude that the phase described is Mitosis, specifically anaphase, based on the observations of chromatids separating and moving toward opposite poles.
