Correct answer: D. Point mutation
- A. Polyploidy
- B. Transmutation
- C. Inversion
- D. Point mutation
Explanation
Phenylketonuria is characterized by a mutation causing the loss of function of the hepatic enzyme phenylalanine hydroxylase through a mutation in the genome. Point mutation occurs when one base pair has been altered, added, or deleted from DNA or RNA. Hence, Phenylketonuria is an example of point mutation.
