Any gene that can transform a normal cell into a tumor cell is called a(n) ____.
A) proto-oncogene
B) oncogene
C) neoplasm
D) checkpoint gene
E) carcinoma
Oncogene
A gene that has the potential to cause cancer, usually by being mutated or expressed at high levels.
Tumor Cell
A cell that has undergone genetic changes enabling it to divide uncontrollably and possibly lead to cancer.
Checkpoint Gene
A gene that regulates cell cycle checkpoints to ensure cells do not divide unless certain conditions are met, playing a key role in preventing cancer.

Final Answer :
B
Explanation :
An oncogene is a gene that has the potential to cause cancer. When it is mutated or overexpressed, it can transform a normal cell into a tumor cell. Proto-oncogenes are normal genes that can become oncogenes if they are mutated or expressed inappropriately. Neoplasm and carcinoma are general terms used to describe tumors, but do not specifically refer to the genes involved in their development. Checkpoint genes are involved in regulating the cell cycle and preventing the formation of cancerous cells, so they would not be considered genes that can transform normal cells into tumor cells.
