Questions & Step-by-Step Solutions

What type of mutation involves the substitution of one base pair for another?
Correct Answer: Point mutation
  • Step 1: Understand what a mutation is. A mutation is a change in the DNA sequence.
  • Step 2: Learn about base pairs. DNA is made up of pairs of bases (like A-T and C-G).
  • Step 3: Know that a point mutation is a specific type of mutation.
  • Step 4: Realize that a point mutation means one base pair is replaced with another base pair.
  • Step 5: Understand that this substitution can change one amino acid in a protein, which can affect how the protein works.
