The correct Answer is:
To answer the question regarding the term applied to the gene mutation where a base is replaced by another base, we can break down the solution into the following steps: ### Step-by-Step Solution: 1. **Understanding Gene Mutations**: - Gene mutations are changes in the nucleotide sequence of DNA. These changes can occur in various forms, and it is essential to identify the specific type of mutation being referred to in the question. 2. **Identifying the Options**: - The question provides four options: 1. Duplication 2. Aneuploidy 3. Euploidy 4. Substitution 3. **Analyzing Each Option**: - **Duplication**: This refers to a mutation where a segment of DNA is duplicated, resulting in an extra copy of that segment. This does not involve the replacement of one base with another. - **Aneuploidy**: This term describes a condition where there is an abnormal number of chromosomes, either through the gain or loss of one or more chromosomes. It does not pertain to the replacement of bases. - **Euploidy**: This refers to a condition where there is a gain or loss of one complete set of chromosomes. Like aneuploidy, it does not involve base replacement. - **Substitution**: This is the term used when one base in the DNA sequence is replaced by another base. This is the specific mutation type that the question is asking about. 4. **Conclusion**: - After analyzing all the options, the correct term that applies to the gene mutation where a base is replaced by another base is **Substitution**. ### Final Answer: The term applied to the gene mutation where a base is replaced by another base is **Substitution**. ---
