Question

multiple choice question which phase of the cell cycle is shown in the box labeled a? prophase anaphase metaphase telophase photos © michael abbey/science source.

Explanation:

To determine the cell cycle phase in box 'A', we analyze the stages:

• Prophase: Chromosomes condense, nuclear envelope breaks down, but chromosomes aren’t aligned at the equator.
• Anaphase: Sister chromatids separate and move to opposite poles.
• Metaphase: Chromosomes align at the cell’s equatorial plane (metaphase plate), and spindle fibers attach to centromeres. The image labeled 'A' shows chromosomes lined up in the middle, matching Metaphase.
• Telophase: Chromosomes decondense, nuclear envelopes reform, and cytokinesis begins.

Answer:

C. Metaphase
