Cell Cycle Progression

Cell Replication

1

Excess production of which proteins result in excess cell proliferation?

1

Proto-oncogene stands for "Early Cancer Gene" because the normal version of this gene can be mutated into a cancer causing gene.

1

Increasing the amount of HER2 receptors in a cell increases the amount of signals being sent which then decreases the rate of cell proliferation.

1

When there is a small amount of DNA damage detected, which proteins are activated to inhibit the cell cycle progression?

1

When there is a small amount of DNA damage detected and the cell cycle is paused, which proteins start repairing the damaged DNA?

1

When a large amount of DNA damage is detected, which proteins are activated to induce apoptosis?

1

The most mutated gene in all cancers is:

1

The site is the origin of the tumor while the site is where the tumor has traveled to.

1

Cancer cells travel through the or vessels.

1

Metastasis relies on more and less of cells.

1

1. ❌
2. ❌
3. ❌
4. ❌
5. ❌
6. ❌

More Replication & Less Apoptosis

Evasion

Loss of Contact Inhibition

Angiogenesis

Emigration

Immigration

1

Cancer cells tend to invade tissues similar to their primary site tissues.

1

Match the 5 Major Types of Cancer with their definitions.
