Question

Quizplus · Accepted Answer

The loss of tumor suppression in a cell is usually the result of the deletion of a tumor suppressor gene. Tumor suppressor genes are responsible for regulating cell growth and division, and when they are deleted or mutated, they cannot perform their normal function, which can lead to the development of tumors. Translocations and inversions, while they can cause changes in gene expression, are less likely to result in the loss of tumor suppression. Activation of a proto-oncogene by a virus can also contribute to tumor formation, but it is not the most common cause of tumor suppression loss.
