  4. Duplication mutation

Questions & Step-by-Step Solutions

Which of the following mutations involves a change in a single nucleotide?
  • Step 1: Understand what a mutation is. A mutation is a change in the DNA sequence.
  • Step 2: Learn about different types of mutations. There are several types, but we are focusing on point mutations.
  • Step 3: Know what a point mutation is. A point mutation is a change that occurs at a specific point in the DNA, affecting only one nucleotide.
  • Step 4: Recognize that a single nucleotide change can alter the amino acid sequence of a protein.
  • Step 5: Conclude that the question is asking for a mutation type that changes just one nucleotide, which is a point mutation.
