Below is the base sequence for the normal protein for normal hemoglobin and the base sequence for the sickle cell hemoglobin. ( This is a lot but I am struggling and i'm failing this class.) Normal: GGG CTT CTT TTT Sickle: GGG CAT CTT TTT

a. Transcribe and translate the normal and sickle cell DNA.

b. Identify this as a point or frameshift mutation. Explain.

c. If the base sequence read GGG CTT CTT AAA instead, would this result in sickle cell hemoglobin? Explain.
