Which of the following statements pertaining to oncogenes is CORRECT?

Question

Quizplus · Accepted Answer

Oncogenes arise from mutations that turn proto-oncogenes into oncogenes. Proto-oncogenes are normal cellular genes involved in growth control, but mutations can activate or increase their expression, leading to abnormal cell proliferation and cell cycle progression. A single mutant copy of an oncogene can affect cell behavior even in the presence of a normal counterpart, through mechanisms such as dominant gain-of-function effects or dominant-negative interactions with other proteins. Oncogenes can arise from somatic mutations (i.e., acquired during an individual's lifetime) or, more rarely, from germline mutations (i.e., inherited from one or both parents). However, most germline mutations in proto-oncogenes are often silent or mildly deleterious, as they would otherwise cause embryonic lethality or predispose to cancer in childhood.
