Step by step
Solved in 2 steps
- 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 apoptosisCompare and contrast oncogenes and tumor suppressors. Contrast oncogenes and proto-oncogenes. Describe the types of mutations that convert proto-oncogenes into oncogenes. Summarize some functions of common oncogenes in cell survival and uncontrolled growth. Contrast tumor suppressors to oncogenes. Describe the types of mutations in tumor suppressors that are found in common cancers. Summarize the functions of common tumor suppressors in cell survival and cell growth.Describe the genetic changes that inactivate tumor-suppressor genes.
- Match each definition with the corresponding term concerning genes involved in tumor formation. Proto-oncogenes Oncogenes Tumor suppressor genes Haploinsufficiency Answer Bank a gene whose function drives uncontrolled cell division and tumorigenesis a gene regulating cell division that can be mutated into a tumorigenic form a gene that protects a cell from progressing toward cancer a condition in which a single copy of a gene fails to produce enough gene product for normal functionTissues and differentiation a)Explain what is meant by termination and differentiation ).b) Explain the difference between an oncogenic and a tumour suppressor gene and describe how they are involved in the onset of cancer1. a)Proteins that stimulate/promote progression through the cell cycle are encoded by (oncogenes or tumor suppressor genes). Boldface one. b)Proteins that inhibit progression through the cell cycle are encoded by (oncogenes or tumor suppressor genes). Boldface one. c)What is the difference between a proto-oncogene and an oncogene? d)To cause cancer, proto-oncogenes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one. e)To cause cancer, tumor suppressor genes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one.
- Tissues and differentiation: a) Explain what is meant by determination and differentiation b) Explain the difference between an oncogene and a tumor suppressor gene and describe how they are involved in the development of cancerOne of the major characteristics of cancer is uncontrolled proliferation of cells. There are several more characteristics of cancer, name TWO more:Define oncogene, proto-oncogene, and tumor-suppressor gene.
- Describe the key characteristics of cancer.Out of these 8 hallmarks ( sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, deregulating cellular energetics and metabolism, and avoiding immune destruction). Rank them from least important to most for cancer development. Explain in 2-3 sentences how.Explain why mutations in tumor suppressor genes are recessive (both copies of the gene must be defective for the regulation of cell division to be defective), whereas mutations in oncogenes are dominant.
