Dr. Thomas Doetschman, Ph.D., examines the embryonic cells used to study and implant mutated and disease genes; if the mutated gene successfully imbeds itself into a sperm or egg cell, the resulting rat that is born will be studied to research the effects of that same disease genes in humans. CRISPR CAS9 is technology that allows the splicing of genes to both remove and replace particular DNA strands. CRISPR can affect either just the patient or his descendants as well, depending on the technique used.
