the oncogenes, which function as positive growth regulators, and the tumor suppressor genes, which function as negative growth regulators.

Oncogenes cause cells to replicate out of control and can lead to cancer. Tumor suppressor genes represent the opposite side of cell growth control, normally acting to inhibit cell proliferation and tumor development.
The development of antibiotics has revolutionized the treatment of infectious diseases. However, antibiotic overuse is a major contributor to the development of antibiotic-resistant bacteria. Antibiotic resistance is a genetic trait.
