Mitosis and Cytokinesis

2. Cell Reproduction Interphase Mitosis (Division) Cytokinesis (Division)
Cell growth, DNA synthesis, Growth and Preparation
Mitosis (Division)
dividing the nucleus into two daughter nuclei
Cytokinesis (Division)
separating the organelles and the cytoplasm

4. Mitosis
Mitosis is a continuous process that can be observed in four stages:
Prophase
Metaphase
Anaphase
Telophase

5. Prophase 1 Chromosomes begin to condense
The nuclear membrane breaks down.
Spindle which is made up of several spindle fibers form.
run at a right angle to the cell’s equator.
An organelle called the centrosome helps assemble the spindle.
animal cells includes a pair of centrioles
centrosomes move to opposite poles of the cell

7. Metaphase Chromosomes are packaged into their most condensed form.
Nuclear membrane is fully dissolved
Chromosomes move to the center of the cell
Spindle fibers form a link between the poles and the centromere of each chromosome.

9. Anaphase Spindle fibers shorten
Sister chromatids move toward opposite poles as the spindle fibers shorten.
Each pole now has a full set of chromosomes.

11. Telophase
A nuclear envelope forms around the chromosomes at each pole of the cell.
Chromosomes now uncoil.
The spindle dissolves.
Mitosis is complete.

13. Cytokinesis The cytoplasm is separated Two daughter cells are formed
Have half of the parent’s cytoplasm and organelles
Genetically identical diploid cells
After cytokinesis, each cell enters the G1 stage of interphase.

15. Summary The life of a eukaryotic cell cycles through;
Growth, DNA replication
preparation for cell division
division of the nucleus and cytoplasm
Mitosis is a continuous process that includes four stages:
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
the cell membrane grows into the center of the cell and divides it into two daughter cells
each daughter cell has about half of the parent’s cytoplasm and organelles
