The mutation resulting in sickle cell disease changes one base pair of DNA so that a codon now codes for a different amino acid, making it an example of a missense mutation.

This is what I believe it is since we're obviously talking about an animal cell and NOT a plant cell like it says. Animal cells do not contain chloroplast.
