Oncogenes are the cancer causing genes in cell but they do not express usually. This is because the presence of
A
proto-oncogene
B
tumor suppressor gene
C
transcription factor
D
None of the above
Explanation: 

Detailed explanation-1: -Cancer can arise when a proto-oncogene is mutated, changing it into an oncogene and causing the cell to divide and multiply uncontrollably. Some oncogenes work like an accelerator pedal in a car, pushing a cell to divide again and again.

Detailed explanation-2: -Oncogenes refer to those genes whose alterations cause gain-of-function effects, while tumor suppressor genes cause loss-of-function effects that contribute to the malignant phenotype.

Detailed explanation-3: -Oncogenes are the main genes contributing to the conversion of normal cells to cancer cells and tumor-suppressive genes block the development of cancer. The way they both act is complicated and needs further investigation to fully elucidate cancer pathways and carcinogenesis.
