Suppose that a gene has a mutation that changes one nucleotide. Because of this one nucleotide change, the mRNA produced from this gene has a slightly different sequence compared to the mRNA produced from the unaltered/non-mutated gene. However, the resulting protein produced from both of these gene versions is exactly the same. This type of mutation would be classified as a missense mutation. degenerate mutation. silent mutation. nonsense mutation. frameshift mutation.

Which of the following mutations in the protein-coding region of a gene is more likely to lead to complete loss of function of the encoded protein: an insertion of six nucleotides or a deletion of two nucleotides? Briefly explain your answer.

Mutation is NEVER NECESSARY for finding optimal solutions to a problem.    True  False

Mutations can arise in the absence of a mutagen. please explain your answer  true false

Define mutation. Understand classification of major types of mutations.

Exposure to various chemicals can cause DNA mutations. Classify the examples as representative of transition, transversion, or nsertion/deletion mutations. Transition replacement of T:A: with C:G treatment with nitrogen mustard causes this type of mutation oxidative deamination via nitrous acid causes this type of mutation treatment with 5-bromouracil causes the replacement of A:T with G:C Transversion replacement of G:C with T:A Answer Bank Insertion/Deletion the removal of one or more base pairs treatment with proflavin causes this type of mutation
