LESSEU Some factors have been proven to increase the risk of mutations occurring. Which of these is NOT a factor that increases the risk of mutations? Gamma rays Tar from cigarette smoke Radio waves Which type of mutation has occurred in the image below? * hp OX-rays

Compare 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.

As discussed, the overall rate of mutations in humans is estimated to be about 1 × 10−8 mutations per base pair per generation. How many new mutations would you expect each person to carry, on average, based on this mutation rate? Other studies have estimated that each person carries about 100 new loss-of-function mutations. How does this number compare with your estimate of the number of mutations based on the mutation rate? What might account for any differences?

Is a random mutation more likely to be beneficial or harmful?Explain your answer.

Which of the following is NOT true about mutations?   A. Mutations can be harmful but not beneficial to the cell  B. Nucleotide substitution in DNA can cause nonsense mutations C. Nucleotide substitution in DNA can cause missense mutations D. Mutagens increase the rate of mutation, but mutations are still random  E. Nucleotide insertion or deletion in DNA can cause frameshift mutations

What type of mutation causes the "mutant" variety of the PTC gene?  a A point mutation which lead to a nonsense mutation  b A addition mutation which lead to a frameshift  c A substitution mutation which lead to a missense mutation  d A deletion mutation which lead to a SNP mutation

What are point mutations? Of the different mutations, which is the most deleterious? Justify your answer with suitable genetic disease.

List two specific causes of DNA mutations.  - environmental agents like ultraviolet light or ionizing radiation - chemicals

Which of the following types of mutations will have the most devastating effect on a cell?A.frameshift mutationB. missense mutationC. nonsense mutationD. silent mutation

If you have a mutation in your skin cells from falling asleep in a tanning bed, how will this affect your offspring? Group of answer choices   It won't affect them because mutations cannot be passed down to offspring It will affect their entire body because their entire body grew out of the fertilized egg It will affect your offspring's skin cells only It may affect them, depending on whether those particular skin cells are passed on to them It won't affect them because the mutation is not in a gamete
