Mitosis (Cell Division) Lili Margolin, Devon Phinney, Ariana Paone, Madison Nadeau Interphase The DNA of each chromosome replicates itself. This happens before the process of Mitosis begins. Prophase (First Phase) Chromosomes condense
SLIDE 2
SLIDE 3
Prophase (First Phase)
- Chromosomes condense
and become visible
- Chromosomes form into
two strands called Chromatids
- Two Chromatids are held
together by the centromere
- Spindle apparatus forms
at opposite sides (poles)
SLIDE 4
Metaphase
- Nuclear envelope and
nucleolus disappear
- Spindle fully develops
- Chromosomes move
until they attach to the spindle fibers from opposite sides
- Chromosomes align
facing the spindle poles
SLIDE 5
Anaphase
- Centromeres break apart in the cell
- Chromosomes split and are dragged toward
the centrioles, which are on opposite sides
- f the cell, by spindle fibers
- Cleavage furrow appears to begin to divide
the cell
SLIDE 6
Telophase
- The nuclear envelope and both nuclei
appear in the cell
- The cytoplasm and organelles divide
equally for each of new cells
- By the end of telophase
the cell has divided into two daughter cells, each having identical genetic characteristics
- Cell division is complete
:)
SLIDE 7
Cytokinesis
- The division of
- cytoplasm. This
completely separates the two new identical daughter cells after the division is complete
