Which is NOT a phase of mitosis?a.prophase                          b.anaphase                          c.interphase

Identifying the Stages of Mitosis

1. Understanding Mitosis: Mitosis is the process by which a cell divides its nucleus and genetic material, resulting in two identical daughter cells. The main phases of mitosis are:

   • Prophase
   • Metaphase
   • Anaphase
   • Telophase

2. Examining the Options:

   • a. Prophase: This is indeed a phase of mitosis where the chromatin condenses into chromosomes, and the nuclear envelope begins to break down.
   • b. Anaphase: This is also a phase where the sister chromatids are pulled apart to opposite poles of the cell.
   • c. Interphase: This is not a phase of mitosis but rather the phase that precedes mitosis, during which the cell prepares for division by replicating its DNA and organelles.

Final Answer

The correct option is c. Interphase, which is NOT a phase of mitosis.
