Mitosis in moss plants could be far more similar to animal cell division than previously thought
Mitosis, a key part of the cell cycle, involves a series of stages (prophase, metaphase, anaphase, and telophase) that facilitate cell division and genetic information transmission. Centrosomes and microtubules play pivotal roles in orchestrating this complex process, ensuring the successful replication of cells.
When the cell is ready to divide it enters M phase, which consists of mitosis (division of genetic material) and cytokinesis (division of the cytoplasm). Cells that exit the cell cycle during interphase enter a non-dividing state called G₀.
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.
