Question

Which of these mutations most likely results in the mutated hemoglobin gene?

Answer 1

Answer: C. Substitution

Explanation:

Substitution is a type of mutation in which a base or amino acid is replaced by another. For example in sickle cell disease, the mutated sickle haemoglobin results from a point mutation of a single amino acid substitution in which a valine residue replaces a glutamate residue at the sixth position in the two beta chains.
