Question

1. Distinguish between oncogenes and proto-oncogenes.

a. Distinguish between oncogenes and proto-oncogenes. Oncogenes are genes that induce or maintain uncontrolled cellular proliferation associated with cancer. They are mutant forms of proto-oncogenes, which normally function to regulate cell division.

b. Proto-oncogenes are genes that induce or maintain uncontrolled cellular proliferation associated with cancer. They are mutant forms of oncogenes, which normally function to regulate cell division.

2. In what ways can proto-oncogenes be converted to oncogenes?

a. translocations b. point mutations c. gene amplification d. repositioning of regulatory sequences
