The Cell Cycle Flashcards
What are the 3 stages of the cell cycle
Interphase - resting phase, no Division takes place
Nuclear Division- when the nucleus divides into 2(mitosis ) or 4 (meiosis)
division of the cytoplasm -
What’s cancer
a group of diseases caused by damage to the genes that regulate mitosis and the cell cycle
What is cancer the result of
Damage to the genes that regulate mitosis and the cell Cycle. This leads to uncontrolled growth and division of cells.
As a consequence, a group of abnormal cells, called a tumour, develops and constantly expands in size
What’s difference between malignant rumours and benign tumours
Malignant tumours grow rapidly, are less compact and are more likely to be life threatening
Benign - grow slower, are more compact and less likely to be life threatening
How do drugs used to treat cancer disrupt the cell cycle
Preventing dna from replicating
Inhibiting the metaphase stage of mitosis by interfering with spindle formation
Why do people loose hair with cancer
As cancer cells have a fast rate of division, they are damaged to a greater degree than normal cells. Those normal body cells such as hair producing cells, that divide rapidly are also vulnerable to damage
