Saturday Genetics Quiz #25: Gene Therapy Part 1
This week’s genetics quiz question:
What are the different approaches for correcting faulty genes?
Answers:
1. A normal gene may be inserted into a nonspecific location within the genome to replace a nonfunctional gene. This approach is most common.
2. An abnormal gene could be swapped for a normal gene through homologous recombination.
3. The abnormal gene could be repaired through selective reverse mutation, which returns the gene to its normal function.
4. The regulation (the degree to which a gene is turned on or off) of a particular gene could be altered.
