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 ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
