Explanation:

A. Mitosis has four well - known phases based on cell and chromosome behavior.
B. DNA replication occurs before mitosis starts in interphase.
C. Chromatin condenses to form chromosomes during cell division.
D. In anaphase, sister chromatids are pulled to opposite poles.
E. Centrioles help in forming the spindle fibers for chromosome movement.
F. A new nuclear membrane forms during telophase as the cell prepares to divide.

Answer:

A. Prophase, Metaphase, Anaphase, Telophase
B. Interphase
C. Chromatin is the uncondensed form of DNA, and it condenses to form chromosomes during cell division.
D. Anaphase
