Prophase
Chromosomes become visable, nuclear envelop dissolves, spindle forms, chromatin starts condensing
Prophase is the first stage of mitosis, which is the process of cell division. During prophase, several important events occur within the cell to prepare for division.
1. Chromosome Condensation: The long and stringy chromosomes that are present in the nucleus of a cell begin to condense and coil tightly during prophase. This makes them easier to move and manipulate during division.
2. Mitotic Spindle Formation: Within the cell, a structure called the mitotic spindle begins to form. This structure is made up of microtubules that will be used to move the chromosomes around during the division process.
3. Nuclear Envelope Breakdown: The nuclear envelope, which normally surrounds and protects the nucleus of the cell, begins to break down during prophase. This allows the chromosomes to be exposed and accessible to the mitotic spindle.
Overall, prophase is a crucial stage in mitosis as it prepares the cell for successful division. It ensures that the genetic material is condensed and organized properly, and that the necessary structures are in place to move the chromosomes around.
