Answer the following question given this paragraph: The first and longest phase of mitosis is prophase . During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell. As the centrioles move, a spindle starts to form between them. The spindle, shown in Figure below , consists of fibers made of microtubules. Q: Chromatin condenses into chromosomes during prophase, the first and longest phase of what process? Choices: - reproduction - apoptosis - meiosis - mitosis A:
mitosis
