1
Q
The 4 Bases of DNA
A
Adenine
Thymine (In mRNA Uracil)
Guanine
Cytosine
2
Q
2 categories of cancer genes
A
Dominant: proto-oncogenes
Recessive: tumor suppressor
3
Q
Gain-of-function mutations
A
altered or unregulated activity of a “proto-oncogene” leads to tumorigenesis
4
Q
Loss-of-function mutations
A
loss of activity of tumor suppressors results in unregulated pathways and tumorigenesis
5
Q
Type of cell that tumors originated from
A
Carcinoma- epithelial cells Sarcoma- connective tissue cells Lymphoma and Leukemia- blood stream Germ cell tumors- Testicle and ovary Blastomas- immature cells or embryonic tissue
