To perform an in vivo gene therapy treatment, cells are removed from the patient's body, normal genes are added to them, and then the cells are returned to the patient's body.
A chromosome normally has the following sequence of genes: f-g-h-i-j-k-l-m. Upon testing, an individual is found to have the following sequence: f-g-h-i-j-k-k-j-i-l-m. What kind(s) of chromosomal mutation(s) does this chromosome have? Check all that apply.
