  1. Silent mutation
  2. Nonsense mutation
  3. Missense mutation
  4. Frameshift mutation

Correct Answer: Missense mutation

Solution: 

A missense mutation results in a change in one amino acid in the protein sequence due to a change in a single nucleotide.

Questions & Step-by-Step Solutions

Which type of mutation results in a change in a single amino acid in a protein?
Correct Answer: missense mutation
  • Step 1: Understand what a mutation is. A mutation is a change in the DNA sequence.
  • Step 2: Learn about nucleotides. Nucleotides are the building blocks of DNA.
  • Step 3: Know that DNA is made up of sequences of nucleotides.
  • Step 4: Recognize that a change in a single nucleotide can affect the protein made from that DNA.
  • Step 5: Identify the types of mutations. One type is called a missense mutation.
  • Step 6: Understand that a missense mutation changes one nucleotide, which can change one amino acid in the protein.
  • Step 7: Conclude that a missense mutation is the type of mutation that results in a change in a single amino acid.
