The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Prophase**: Prophase is the first stage of cell division in both mitosis and meiosis. It is crucial to know what happens to chromosomes during this phase. 2. **Composition of Chromosomes**: During prophase, the genetic material in the nucleus consists of DNA and proteins. These components are essential for the formation of chromosomes. 3. **Formation of Chromatin**: The DNA and proteins in the nucleus condense to form chromatin fibers. This is an important transition where the genetic material starts to become more organized. 4. **Condensation into Chromosomes**: As prophase progresses, these chromatin fibers further condense and coil tightly, leading to the formation of distinct chromosomes. This process is crucial for ensuring that the genetic material is properly segregated during cell division. 5. **Characteristics of Chromosomes in Prophase**: At this stage, the chromosomes are not only formed but also enlarged in size and highly coiled. This coiling is necessary for the chromosomes to be efficiently separated later in the cell division process. 6. **Conclusion**: Therefore, during prophase, chromosomes are large and coiled, indicating that they have undergone significant structural changes to prepare for cell division. **Final Answer**: During prophase, chromosomes are large and coiled. ---
