Oncogenes and Tumor Suppressor Genes NOTES Cancer
... Unlike oncogenes, tumor suppressor genes generally follow the "two-hit hypothesis", meaning that both alleles that code for a particular protein must be affected before an cancer-causing effect is seen. This is because if only one allele for the gene is damaged, the second can still produce the corr ...
