검증된 단계별 안내1
Understand the types of mutations listed: Point mutations, Induced mutations, Frameshift mutations, and Prototroph mutations.
Define each type of mutation: Point mutations involve a change in a single nucleotide base pair. Induced mutations are caused by external factors like chemicals or radiation. Frameshift mutations result from insertions or deletions of nucleotides that change the reading frame of the genetic code.
Recognize that 'Prototroph mutations' is not a standard term for a type of DNA mutation. Instead, 'prototroph' refers to an organism that can synthesize all compounds needed for growth, unlike auxotrophs which require additional nutrients.
Identify that the question is asking for the option that is not a type of DNA mutation. Based on the definitions, 'Prototroph mutations' does not fit the category of DNA mutations.
Conclude that 'Prototroph mutations' is the correct answer to the question, as it is not a recognized type of DNA mutation.
