Eukaryotic Somatic (Body) Cell Division
Stages of Cell Cycle• Interphase
– G1 = Growth– S = DNA replication– G2 = Prepare for Mitosis
• M Phase– Mitosis = Division of Nucleus
• Prophase • Metaphase• Anaphase• Telophase
– Cytokinesis = Division of Cytoplasm

MITOSIS
REPRODUCTION OF BODY (somatic) CELLS
PRODUCES
2 IDENTICAL DIPLOID CELLS

Interphase• Cell Grows
• DNA is Replicated
• Cell gets ready to divide
![Page 6: This is the Cell Cycle · This is the Cell Cycle M Phase. Eukaryotic Somatic (Body) Cell Division Stages of Cell Cycle •Interphase –G1 = Growth –S = DNA replication –G2 =](https://reader034.vdocuments.net/reader034/viewer/2022050217/5f635017905b745fc577c30f/html5/thumbnails/6.jpg)
Prophase• 1St phase of Mitosis• Chromosomes
become visible when chromatin condenses into chromosomes
• Nuclear Membrane & Nucleolus Disappear
• Centrioles move to the poles & produce spindle fibers
EARLY LATE
![Page 7: This is the Cell Cycle · This is the Cell Cycle M Phase. Eukaryotic Somatic (Body) Cell Division Stages of Cell Cycle •Interphase –G1 = Growth –S = DNA replication –G2 =](https://reader034.vdocuments.net/reader034/viewer/2022050217/5f635017905b745fc577c30f/html5/thumbnails/7.jpg)
Metaphase• 2nd Phase of
Mitosis• Spindle Fibers
attach to the Centromeres
• Chromosomes Line up in the Middle/ Equator

Anaphase• 3rd Phase of
Mitosis• Sister
Chromatids are Pulled Apart (separated) to opposite poles of the cell
![Page 9: This is the Cell Cycle · This is the Cell Cycle M Phase. Eukaryotic Somatic (Body) Cell Division Stages of Cell Cycle •Interphase –G1 = Growth –S = DNA replication –G2 =](https://reader034.vdocuments.net/reader034/viewer/2022050217/5f635017905b745fc577c30f/html5/thumbnails/9.jpg)
Telophase• 4th Phase of
Mitosis• Nuclear
Membrane & Nucleolus Reform
• Chromosomes Unwind into Chromatin
• Cell begins to pinch

Cytokinesis• Last Phase of Cell
Cyle
• Cytoplasm Divides
• 2 Identical daughter cells form with the SAME number of chromosomes as parent cell
Occurs during Telophase

MITOSIS & CYTOKINESIS
END RESULT:
Produces 2 Genetically Identical
Diploid Body (Somatic) Cells
