What is hypoxia

What are the stages of the cell cycle

Interphase

Prophase

Metaphase

Anaphase

Telophase

What happens in G1, S and G2

G1 is where the cell grows

S DNA duplication

G2 cell growth

Why do you not want to treat at the end of G2

DNA is unravelled so easier to destroy unwanted genetics

Does a well differentiated tumour mean more aggressive or less aggressive

Less aggressive
