mitosis worksheet and diagram - TradeSphere
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). 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.
Understanding the Context
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. 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. Mitosis (la fase M) El proceso de mitosis o división celular, también se conoce como fase M. Aquí es donde la célula divide su ADN, que antes copió, así como su citoplasma para formar dos nuevas células hijas idénticas. La mitosis consta de cuatro fases básicas: profase, metafase, anafase y telofase. The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
