The Cell Cycle and Mitosis
Transcript of The Cell Cycle and Mitosis
Telophase & Cytokinesis
G1 - primary or first growth
S - synthesis
G2 - secondary or second growth
The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.
S - Synthesis
S is when the DNA gets synthesized, or replicated.
G2 is secondary or second growth.
In G2, organelles enlarge and prepare to become two seperate cells.
Anaphase is where the chromosomes are split apart from a line in the middle if the cell.
This is the last phase of mitosis.
In this phase, the nuclear membrane reforms,
nucleoli reappear, and chromosomes unwind
G1 is primary or first growth.
In G1, the organelles perform their functions and go about their normal activities.
There are three parts of interphase:
Spindle fibers extend from poles and connect to center of cell.
Mitosis is ordinary cell division.
Cells divide to maintain the same number of cells in an organism.
chromosomes move randomly until they attach to spindle fibers.
chromosomes align at metaphase plate in middle of cell
