Cancer causing genes are called ________.

a. transformation genes

b. tumor suppressor genes

c. oncogenes

d. mutated genes

Cancer cells are just altered versions of normal ones. This transformation begins during the cell cycle with changes in DNA sequence, which then affects gene regulation.

Option (c) is given as 'oncogenes.This is correct because these are the cancer-causing genes. These are mutated from their original form, proto-oncogenes, in cancer or tumour cells. As a result, option (c) is the right answer.

Option (a) is given as 'transformation genes'It is incorrect .because when a foreign gene is incorporated into a cell's genetic material, the genetic material of the cell is transformed. It is not a cancer-causing substance.

Option (b) is given as 'tumor suppressor genes'It is incorrect.because they are negative gene regulators that prevent tumour cells from forming

Option (d) is given as 'mutated genes'. It is incorrect.Because the nucleotide sequence of these genes is constantly changing.
