Mitosis: Asexual Cell Reproduction
Mitosis: Making 2 new cells
from a single
original. Genetically Identical
5 Stages
• Interphase
• Prophase
• Metaphase
• Anaphase
• Telophase
• IPMAT
Interphase
“In between Cell Divisions”
• Most of the cell life cycle
• Growth and other life processes
• DNA duplicates
Prophase
“Prepare to Divide”
1. Chromatin condenses to form chromosomes
2. Centrioles migrate to opposite poles
3. Spindle fibers form and attach near centromere
4. Nuclear envelope disappears
Metaphase
“Chromosomes in the Middle”
• Chromosomes line up across the middle
• Spindle fibers connect centromere to centriole
Anaphase
“Chromosomes Apart”
• Sister chromosomes separate at centromere
• Move to opposite poles
Telophase
“End with two daughter cells”
• Cytokinesis – division of the cytoplasm– Pinching in with animal cell– Cell plate (new cell wall) forms in plant cell
• Chromatin separates and returns to loose state
