The processes you described are stages of cell division, specifically mitosis, which is a method of asexual reproduction and growth in eukaryotic cells. Here’s a brief overview of each stage mentioned:
1. **DNA is replicated:** This occurs during the S phase (Synthesis phase) of interphase, preceding mitosis. Each chromosome is replicated to form two sister chromatids, which are identical copies of DNA connected at a region called the centromere.
2. **Chromosomes align in the middle of the cell:** During metaphase, the chromosomes (now consisting of sister chromatids) line up along the metaphase plate (the cell's equatorial plane). This alignment ensures that each new cell will receive one copy of each chromosome during cell division.
3. **Paired chromosomes separate at protein structures:** This describes the anaphase stage, where the sister chromatids are pulled apart by the spindle fibers attached to the centromeres. The protein structures referred to are the spindle fibers that facilitate this movement.
4. **The cell separates into two new cells:** This occurs during cytokinesis, which follows mitosis (specifically, telophase). The cytoplasm divides, forming two distinct daughter cells, each with a complete set of chromosomes.
In summary, these stages outline key events in the cell cycle, culminating in the division of one cell into two daughter cells.
