Question
Indicate whether each of the following descriptions better applies to proto-oncogenes (P) or tumor suppressor genes (T). Your answer should be a four-letter string composed of letters P and T only, e.g. PPPT ()Cancer mutations in these genes are usually recessive. ()Cancer mutations in these genes include gene duplications. ()Cancer mutations in these genes are usually dominant. ()Cancer mutations in these genes are commonly in the form of nonsense (truncating) mutations that abort protein synthesisExplanation / Answer
T P P T
These answers are based on the research findings that generally the mutations in the tumor suppressor genes are recessive due to nonsense mutations. However in case of proto-oncogenes, the mutations are generally dominant having gene duplications
