- Gene mutations can be classified in two major ways:(1) hereditary or germline mutations that are inherited from a parent and are present throughout a person’s life in virtually every cell in the body.(2) acquired or somatic mutations that occur at some time during a person’s life and are present only in certain cells, not in every cell in the body.If there is no family history of a particular disease but a child has the disease then it may have arisen due to a(n) ________ mutation early during development. A) acquired B) inherited C) silent D) transitionarrow_forwardThe rb gene encodes a protein that inhibits E2F, a transcriptionfactor that activates several genes involved in cell division.Mutations in rb are associated with certain forms of cancer,such as retinoblastoma. Under each of the following conditions,would you expect the cancer to occur?A. One copy of rb is defective; both copies of E2F are functional.B. Both copies of rb are defective; both copies of E2F arefunctional.C. Both copies of rb are defective; one copy of E2F is defective.D. Both copies of rb and E2F are defective.arrow_forwardThe genetic alteration responsible for sickle-cell anemia in humans involves: a transition mutation from A to G, substituting glutamic acid for valine in a-globin a transversion mutation from T to A, substituting valine for glutamic acid in b-globin a transition mutation from T to C, substituting valine for glutamic acid in b-globin a transversion mutation from G to C, substituting glutamic acid for valine in a-globin a frameshift mutation of one ATC codon, removing glutamic acid from b-globinarrow_forward
- What is a mutation? How does a mutation lead to an altered phenotype? Describe two specific types of mutations.arrow_forwardHuntington disease (HD) is an inherited neurodegenerative disorder characterized by gradual, irreversible impairment of psychological, motor, and cognitive functions. Symptoms typically appear in middle age, but onset can occur at almost any age, and the course of the disease can range from 15 to 20 years. The molecular basis of HD is becoming better understood, and the genetic mutation has been traced to a gene that encodes a large protein of unknown function. In individuals who will not develop HD, a region of the gene that encodes the N-terminus of this protein has a sequence of CAG codons (for glutamine) repeated 6 to 39 times in succession. In individuals with adult-onset HD, this codon (3 nucleotides) is typically repeated 40 to 55 times In those with childhood-onset HD, it is repeated more than 70 times. *codon: refers to the 3 nucleotides that code for amino acid. A small portion of the coding sequence of the HD gene is given below. The nucleotide sequence of the DNA is…arrow_forwardAlthough it is well known that X-rays cause mutations, they are routinely used to diagnose medical problems, including potential tumors, broken bones, and dental cavities. Why is this done? What precautions need to be taken?arrow_forward
- Two types of mutations discussed in this chapter are (1) nucleotide changes and (2) unstable genome regions that undergo dynamic changes. Describe each type of mutation.arrow_forwardOne unexpected result of the sequencing of the human genome was the finding that mutations in a single gene can be responsible for multiple distinct disorders. For example, mutations in the RET gene can cause two different types of multiple endocrine neoplasias, familial medullary thyroid carcinoma, and Hirschsprung disease. How do you think mutations in a single gene can have such diverse effects?arrow_forwardWhat is the difference between a germline mutation and a somatic mutation?arrow_forward
- define the term name as Missense mutationsarrow_forwardIn the replica plate experiment, it shows that mutations are random. However, certain environmental stresses (such as high temperature, high salt, and low pH) can increase the mutation rate. QUESTIONS: Does this indicate that mutations are nonrandom, since they increase in response to cell stressors?arrow_forwardProvide one example of a clinical implication of a “silent mutation” that proven to have an effect on the phenotype and provide a brief description of its molecular characteristics?
