Sickle cell anemia is a genetic disorder in which the hemoglobin responsible for transporting oxygen is mis- formed.  The disease begins with a mutation in a __________________  _______, which results in a structural difference in a ______________  ___.

Sickle-shaped red blood cells result from a mutation in the gene that codes or hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below.

What type of mutation is depicted in this sequence?
