Separation of the sister chromatids is a characteristic of which stage of mitosis? a. prometaphase, b. metaphase, c. anaphase, d. telophase.

Step 1: Define the Problem

Identify the stage of mitosis where sister chromatids separate.

Step 2: Break Down the Problem

• Understand the stages of mitosis: prophase, prometaphase, metaphase, anaphase, and telophase.
• Determine the specific stage where sister chromatids are pulled apart.

Step 3: Apply Relevant Concepts

• During anaphase, the sister chromatids are separated and pulled towards opposite poles of the cell.

Step 4: Analysis, Verify and Summarize

• Review the characteristics of each mitotic stage:
  • Prometaphase: Nuclear envelope breaks down, and microtubules attach to kinetochores.
  • Metaphase: Chromosomes align at the metaphase plate.
  • Anaphase: Sister chromatids are separated and move to opposite poles.
  • Telophase: Chromatids arrive at poles, and nuclear membranes start to reform.

Final Answer

c. anaphase
