Goal: Understand How Cells Divide by Mitosis
New Words: mitosis, prophase, metaphase, anaphase, telophase
Interphase
• Increasing cell size and grow
• DNA is replicated
• Production of many organelles and molecules
Prophase
• Nuclear membrane dissolves
• Wind DNA ( chromatin) into chromosomes
• Centrioles and spindle fibers become visible
Metaphase
• Chromosomes line up in the middle of the cell
• Spindle fibers attach to each chromosome at the
centromere
Anaphase
• Spindle fibers pull chromatids apart to opposite
end of the cell
Telophase
Cytokinesis
• Nuclear membrane forms
• DNA unwinds into chromatin
• Centrioles and spindle fibers become non visible
• Cell splits with its own set of chromosomes

Mitosis
Number of cell division?
One
Exchange of genetic material between
chromosomes?
No
Number of functioning cell produced from
the original?
Two daughter cells
Number of chromosomes of daughter cells
compare to parent cells
Equal number
In human is 46 chromosomes
How is the genetic material of final cells
produced?
Identical as the original
Function of cells produced?
• Growth or replacement of body cells
• Same as the parent cells
