Solution

The addition or deletion of a nucleotide base pair can result in a frameshift mutation.

Here's why:

  1. A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three.

  2. "Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein.

  3. If a mutation disrupts this reading frame, then all of the codons (groups of three bases) that come after the mutation will be read incorrectly. This can make the resulting protein function improperly, or not function at all.

  4. Therefore, the addition or deletion of a nucleotide base pair can result in a frameshift mutation, which can have significant impacts on the resulting protein and overall gene expression.
