Answer :
Elephants have twenty pairs of p53 genes, which are tumor suppressor genes; humans only have one pair, making them more prone to cancer when compared to elephants.
What are tumor suppressor genes?
Tumor suppressor genes are genes able to inhibit the development and growth of cancer cells and related tumors, which are generally associated with key points in the cell cycle in order to avoid the uncontrolled proliferation of cancer cells.
Conversely, oncogenes are genes when abnormally expressed that promote the development and differentiation of cancer tumor cells, which are generally growth factors expressed in abnormal tissues or during abnormal phases of the development.
Therefore, with this data, we can see that the tumor suppressor genes such as the p53 gene are able to suppress the development of cancer cells and thus avoid the proliferation of tumors, which is fundamental to controlling this multifactorial disease.
