Question

Explanation:

Identify the stages of the cell cycle and mitosis in order

Describe the key events occurring in each stage

Answer:

Stage	What is Occurring?
Prophase	Chromosomes condense and become visible, the nuclear envelope breaks down, and spindle fibers begin to form.
Metaphase	Chromosomes line up along the middle (equator) of the cell, and spindle fibers attach to the centromeres.
Anaphase	Sister chromatids are separated and pulled by spindle fibers to opposite poles of the cell.
Telophase	Nuclear membranes reform around each set of chromosomes at opposite poles, and chromosomes begin to uncoil.
Cytokinesis	The cytoplasm divides, pinching the cell membrane (or forming a cell plate) to produce two separate, genetically identical daughter cells.
