Explanation:

For question 1: Mitosis has four main phases - prophase, metaphase, anaphase, and telophase. In anaphase, sister chromatids separate and move to opposite poles of the cell.
For question 2: During prophase, chromatin condenses into chromosomes, the nuclear envelope breaks down, and spindle fibers start to form.
For question 3: When DNA condenses, it means that the long, thin strands of DNA coil and fold tightly around histone proteins to form chromosomes, which is essential for proper segregation during cell division.

Answer:

1. Anaphase
2. Chromatin condenses into chromosomes (or nuclear envelope breaks down, or spindle fibers start to form)
3. DNA coils and folds tightly around histone proteins to form chromosomes.
