Prophase:- Nucleus disappears and chromatin fibers condense down into chromosomes. - Chromosomes line up in pairs - Spindle fibers form at opposite ends of the cell
The Cell Cycle
Mitosis
Mitosis (which follows Interphase) has 4 stages: 1. Prophase2. Metaphase3. Anaphase4. Telophase
just remember: PMAT
Anaphase- the pairs of chromosomes are pulled apart til separated. - each end of the cell has a complete set of chromosomes
Telophase- Nuclear envelope and nucleus begins to reform and the chromatin of the chromosomes uncoils.
Metaphase- Chromosomes line up at the middle of the cell (metaphase plate) -The chromatids of each chromosomes are attached to a microtubule which form the spindle.
so what's next? CYTOKINESIS! the actual separation of the newly formed daughter cells!
