Below is the base sequence for the normal protein for normal hemoglobin and the base sequence for the sickle cell hemoglobin. Normal: GGG CTT CTT TTT Sickle: GGG CAT CTT TTT Transcribe and translate the normal and sickle cell DNA.

Below is the base sequence for the normal protein for normal hemoglobin and the base sequence for the sickle cell hemoglobin. Normal: GGG CTT CTT TTT Sickle: GGG CAT CTT TTT Identify this as a point or frameshift mutation. Explain.

Below is the base sequence for the normal protein for normal hemoglobin and the base sequence for the sickle cell hemoglobin. Normal: GGG CTT CTT TTT Sickle: GGG CAT CTT TTT If the base sequence read GGG CTT CTT AAA instead, would this result in sickle cell hemoglobin? Explain.
