Cell Cycle Presentation
JORDAN JONES
Step One ~ Interphase
Function- To move the DNA and other materials in the parent cell into position for cell division.
Result- two daughter cells (new cells) that have a full set of DNA and organelles.
Mitosis = divides the nucleus
Centrioles = trash can looking objects in cells
Spindle Fibers = threads that go from centriole to chromosomes
DNA = in the form of chromosomes
Step Two ~ Prophase
In the nucleus of the cell, DNA forms chromosomes
Nuclear membrane disappears
- Spindle Fibers
Step Three ~ Metaphase
Chromosomes line up in the middle of the cell
Spindle Fibers from centrioles attach to chromosomes
Step Four ~ Anaphase
Chromosomes separate
- Each half is pulled to the opposite end of the cell
- parts of the cell present: Centrioles, Spindle Fibers, DNA, Nucleus
Step Five ~ Telophase
A new nuclear membrane forms around each group of chromosomes (at either end of the cell).
MITOSIS IS FINISHED. THE RESULT IS THE DNA HAS BEEN EQUALLY DIVIDED.
Parts of the cell present: Centrioles, Spindle Fibers, DNA, Nucleus
Step Six ~ Cytokinesis
The parent cell’s cytoplasm is divided between the two daughter cells.
The cell is pinched into two.
- Cytokinesis = divides the cytoplasm
- Parts of the cell present: centrioles, spindle fibers, DNA, nuclear membrane, nucleus.
Results Of The Cycle ~
Two daughter (or new) cells are completely separated.
Each daughter cell has ½ of its parent cell’s cytoplasm.
Each daughter cell is identical to its parent cell except smaller.
- Each daughter cell will go through a period of growth to eventually become as large as the parent cell.
