The Cell Cycle
The cell cycle is a process that leads to the division of a cell to create a new, genetically identical cell.
Purpose in Multicellular
Purpose in Unicellular
The purpose of cell division in multicellular organisms is to grow and replace dying cells.
The purpose of cell division in unicellular organisms in reproduction.
Interphase
How Our Bodies Control the Cell Cycle
Interphase is where the cell grows and prepares for mitosis.
G1: Cells synthesize proteins, make
RNA,
and grow.
Our bodies check for errors in replication throughout the cell cycle. At checkpoints during the process, DNA is checked for errors and corrected. Interphase is the main part of the cell cycle where mistakes can be made. Mistakes can be made and we can lose control of cell division in G1 because this is where RNA and proteins are produced and synthesized.
Synthesis: DNA is copied and replicated.
G2: The cell grows and produces more proteins.
Mitosis
Cytokinesis
The physical process in which two genetically identical cells are made.
The end of the division where the cell is fully divided into two new, genetically identical daughter cells.
Telophase: The division is done and the cells are split into two pieces.
Prophase: DNA condenses into chromosomes and centrioles move into place.
Anaphase: The chromosomes move apart and move the end of the cells.
Metaphase: The chromosomes are
aligned
in the
middle
of the cell.
Cancer
Any malignant growth or tumor caused be abnormal or uncontrolled cell division.
Treatment Options
Breast Cancer
Breast cancer is a tumor that starts in the cells of the breast. It is commonly found in women, but men can also get it. Breast cancer cells can travel in lymphatic vessels and begin to grow in lymph nodes.
- Surgery: Removes the actual tumor from the body.
- Radiation: High energy rays that are targeted to kill cancer cells.
- Chemotherapy: Cancer killing drugs that slow down cell reproduction
- Targeted Therapy: Drugs aimed specifically at cancer cells and do not effect normal cells as much.
Breast Cancer Statistics
Risk Factor of Breast Cancer
- 1 and 8 women will develop breast cancer over their lifetime.
- 1 in 1,000 men are in risk of breast cancer during their lifetime.
- White women are slightly more likely to develop breast cancer than African American women.
- A women's risk of breast cancer is increased if she had a first degree relative with breast cancer.
- 5-10% of breast cancer can be linked to gene mutations.
- About 85% of breast cancer occurs in women who have to family history of breast cancer.
