Which of the following is true of tumor suppressor genes? Group of answer choices a) If this gene is overactive, it becomes an oncogene b) If one of the alleles is mutated, there is usually little effect. Two inactivating mutations are usually required for loss of function (recessive mutation). c) If one copy is lost, the gene no longer functions (dominant mutation) d) Tumor suppressors genes usually cause mitosis or cell growth e) Tumor suppressor genes decrease apoptosis
