Question

Gene therapy

Accepted Answer

some diseases (e.g cystic fibrosis, which causes lung infections and limits breathing ability) result of faulty (mutant) genes
Somatic cell gene therapy - replacing mutant allele with healthy alele in somatic (body) cells so functional allele doesnt pass onto offspring,
Germ line gene therapy - functional allele added to gametes so all somatic cells contain functional allele so can pass onto offspring, illegal - to prevent parents choosing offsprings characteristics

Allele Gene Therapy Somatic Functional Cells Pass Offspring
