2 Genetic Screening Test DNA to detect genetic diseases determines risk of having or passing on a genetic disordercan detect some genes known to cause genetic disorders
3 Gene Therapy Gene Therapy - the replacement of faulty genes Attempts to replace defective or missing genes or add new genes to treat a disease.
4 Gene Therapy Still in the experimental stages Some issues: Inserting gene into correct cell/all cellsDetermining effect on other genesImmune system may respond causing inflammation
5 Cloning Entire organisms can be cloned Clone- genetically identical copy of gene or of an organismSome simple animals can essentially clone themselves by regenerationEx. Sea StarsFirst cloned dog
6 Cloning Process In mammals- scientists swap DNA between cells Unfertilized egg taken from animalEggs nucleus (DNA) removedNucleus (DNA) of animal to be cloned is implanted into eggAfter embryo grows for a couple days it is transplanted into femaleCloning brainpop
8 Dolly the SheepDolly became first cloned mammal from using an adult cell.Led to cloning of pigs, dogs and miceClone may not look like original (many factors influence expression of gene- i.e. environment)Dolly the Sheep brainpop
