Solved in 2 steps
- You suspect a protein that is being expressed has been affected by a mutation. When you examine the fully functional protein you find curiously that it still has retained all of its overall function. A friend of yours doing research with you assures you when examining the genetic data a new mutation does in fact exist in this protein. What is the most likely type of mutation that occurred based on this information? Group of answer choices frameshift mutation silent mutation nonsense mutationPoint mutations arise more commonly than other types of mutations. -True or FalsePeople who have muscular dystrophy have something called a “mutation.” How does that mutation arise? Be sure to show what is happening to DNA and mRNA.
- In humans, sickle-cell anemia and hemophilia represent which type of mutations? Loss of function mutation Gain of function mutation Behavioral Mutation Biochemical mutationDo mutations always cause negative impacts? Why or why not?Two major types of mutations are gene mutation and chromosome mutation. Which mutation is more lethal and why?
- Although 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?X-rays strike a chromosome in a living cell and ultimately cause the cell to die. Did the X-rays produce a mutation? Explain why or why not.Some silent mutations have been found to be associated with disease. Suggest a possible mechanism for this. How would you test this hypothesis?
- What might best explain why the incidence of cancer increases as people age? Select one: a. mutations accumulate as people age b. cell division increases as people age c. protein synthesis increases as people age d. telomerase activity increases as people age e. ATP production increases as people ageCompare and contrast nonsense mutations, silent mutations, and missense mutations including the impact of the mutation on the protein produced. Your answer should be 3-7 sentences sentences long and fully explain how they are similar and what is different between the mutations.Mutations can arise in the absence of a mutagen. please explain your answer true false
