Which phase of mitosis is labeled A in this illustration?Multiple choice question.AnaphaseMetaphaseProphaseTelophase

To determine which phase of mitosis is labeled A in the illustration, we can use the following approach:

1. Identify the Features of Each Phase:

   • Prophase: Chromosomes condense and become visible; the nuclear envelope starts to break down.
   • Metaphase: Chromosomes align at the metaphase plate (center of the cell).
   • Anaphase: Sister chromatids are pulled apart to opposite poles of the cell.
   • Telophase: Chromatids reach the poles; the nuclear envelope starts to reform around each set of chromosomes.

2. Analyze the Characteristics:

   • Look at the alignment of chromosomes, presence of the nuclear envelope, and movement of chromatids to distinguish between the phases.

Final Answer

Without the illustration, I suggest identifying the phase based on the characteristics described above. If labeled A corresponds to aligned chromosomes in the center, it is Metaphase. If chromatids are being pulled apart, it is Anaphase.
