Explain Oncogenes.​

Answer 1

Oncogenes.​

Explanation:

• An oncogene is a gene that has the potential to cause cancer. In tumor cells, these genes are often mutated, or expressed at high levels.
• Most normal cells will undergo programmed form of rapid cell death (apoptosis) when critical functions are altered and malfunctioning.
• An oncogene is a mutated gene that contributes to the development of a cancer.
• In their normal, unmutated state, onocgenes are called proto-oncogenes, and they play roles in the regulation of cell division.Receptor tyrosine kinases
• Examples of oncogenes in this class include the epidermal growth factor receptor (EGFR), platelet-derived growth factor receptor (PDGFR), vascular endothelial growth factor receptor (VEGFR), and human epidermal growth factor receptor 2 (HER2/neu).
