- The Effects of a Mutation are Difficult to Predict Why?For a mutation that does not have a fitness cost to the individuals who carry it, we call the mutation a -synonymous mutation -beneficial mutation -dominant mutation -homologous mutation -neutral mutationSuppose that a gene has a mutation that changes one nucleotide. Compared to the protein produced from the non-mutated gene, the protein produced from this mutated gene has one different amino acid. This newly altered protein provides enhanced resistance to tetracycline (an antibiotic). This type of mutation would be classified as a
- Briefly explain this Statement "Treatment for the genetic disorders by using gene therapy " Please answer at your own words, please (400-500 words).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) transitionSickle cell anemia is a disease caused by a mutation at the genotypic level. A person with two copies of the gene has the disease, but a person with one copy of the gene does not have the disease. The diagram shows how this mutation affects an organism. Use the image to answer the question. The mutation causes the deformity of the red blood cell, the component of blood that carries oxygen throughout the body. The deformed cells can clump together and can clog blood vessels. The parasites responsible for the sickle cell condition are killed in the deformed red blood cells. In which type of environment would carriers of the disease be naturally selected for? A. low altitude B. high altitude C. low population of parasites D. high population of parasites
