Answer

Brief Explanations:

In gene - therapy, first the unhealthy gene is cut from the DNA. Then the normal allele is removed from the chromosome and added to the cells of the person with the disorder. So the missing step is cutting the unhealthy gene from the DNA before step 2.

Answer:

The unhealthy gene is cut from the DNA before step 2.
