Oncogenes are mutated forms of genes. Oncogenes can transform a cell into a tumor cell. Some tumor cells are benign, while others are malignant. How does the presence of an oncogene lead to the formation of a tumor?

|
ATP production is inhibited.

|
|
Cell division is unregulated.
|
|
|
Somatic cell growth is inhibited.
|
|
|
Antibody activity is unregulated.

Explanation:
Detailed explanation-1: -Oncogenes end up promoting uncontrolled cell growth and division, causing normal cells to become cancerous. On the other hand, tumor suppressor genes are genes that code for protein products that regulate and slow down the cell cycle, and also promote apoptosis, which is programmed cell death.
Detailed explanation-2: -Proto-oncogenes are normal genes that, when mutated, become oncogenes-genes that cause a cell to become cancerous.
