1. The diagrams (A and B) below represent the two common types of cancer genes; one diagram illustrates mutation/s in a typical tumor suppressor gene and the other illustrates mutation/s that change a proto-oncogene to an oncogene. No mutant alleles One mutant allele No mutant alleles One mutant allele Two mutant alleles Mutation Mutation Mutation A Normal cell division Excessive cell proliferation B Normal cell division Normal cell division Excessive cell proliferation 1a. Identify which type (tumor suppressor or proto-oncogene to an oncogene) is illustrated by each diagram (A and B) and describe the differences. 1b. Discuss which of the two illustrations above show a cancer gene with allele/s that acts recessively, and which shows a gene with allele/s that act in a dominant fashion.
