Proto-oncogenes can be transformed to oncogenes by all of the following mechanisms except:
A)chemically induced mutagenesis.
B)chromosomal rearrangements.
C)during a viral infection cycle.
D)elimination of their start signals for translation.
E)radiation-induced mutation.

Question

Quizplus · Accepted Answer

The elimination of start signals for translation would not cause a proto-oncogene to transform into an oncogene. The other options (chemically induced mutagenesis, chromosomal rearrangements, viral infection, radiation-induced mutation) can all result in the activation of proto-oncogenes into oncogenes.
