- Define and compare the following types of nucleotide substitutions. Which is likely to cause the most dramatic mutant effect? a. missense mutation b. nonsense mutation c. sense mutationTwo 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.Define mutation. Understand classification of major types of mutations.
- The word mutation is generally considered to be negative. However, is there a positive side to mutations? Briefly explain your answer.Match the relationships to the corresponding concepts. Expanding nucleotide repeat..... Somatic mutation Base substitution Transition Missence mutation Nuetral mutation Mutation Germline mutation Transversion Silent mutation Indels Frameshift mutation Nonsense mutation Inherited change in DNA sequence Loss of function mutation Gain of function mutation Insertions Deletions Reading frame Answer Bank involving the number of repeat sequences often lead to if removes function alteration of single nucleotides are often alter the alters sense codon to stop codon substitution of unlike base alters the amino acid in protein insertions and deletions of sequences are based on type of tissue, can be does not alter function substitution of like base defined as does not alter amino acid in protein if gains functionDefine mutation. Explain why some mutations are harmlessand others can be lethal.
- Explain why STR mutations are found at a much higher frequency than single nucleotide changes?What type of mutation is shown in the diagram? Why do you think this type of mutation is referred to by this term?Induced mutation are characterized by: Select the correct response: Exposure to free radicals that has been deposited in the aqueous phase and diffuses towards the cell that is followed by the inhibition of its replication or transcription, or may cause deletion. Physical and chemical agents that results in the transition, transversion, and framshift mutations of bases and other structural units that affects the overall function of a nucleic acid. Physical and chemical agents that results in the alteration of the electoronic characteristics of the bases and other structural units that affects the overall function of a nucleic acid. Point mutations that results in the transition, transversion, and framshift mutations of bases and other structural units that affects the overall function of a nucleic acid. Physical and chemical agents that results in the alteration base pairing where tautomers are formed affects the overall function of a nucleic acid.
