14.3

Human DNA analysis Alleles can be tested for Beneficial for parents who think offspring might have Tay-Sachs or cystic fibrosis

DNA fingerprinting Look at DNA that has no function Varies a lot from person to person DNA necessary for life is very similar between people

Human Genome project Mapping of DNA sequences Mapping of all human genetic disorders Data is available to EVERYONE

Gene Therapy absent or faulty gene is replaced by normal working gene normally done by a virus research being done for cystic fibrosis patients

 What is normal and what is a disability or disorder, and who decides?  Are disabilities diseases? Do they need to be cured or prevented?  Does searching for a cure demean the lives of individuals presently affected by disabilities?
