Sickle-shaped red blood cells result from a mutation in the gene that codes for 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.
Normal hemoglobin:
T-G-A-G-G-T-C-T-C-C-T-C
Sickle-cell hemoglobin: T-G-A-G-G-T-C-A-C-C-T-C
What type of mutation is depicted in this sequence?
A Substitution
B Insertion
C Deletion
D Frameshift
Option A
Option B
Option C
Option D
