Textbook Question
Chapter 42.3, Problem 1CT
In 2017, scientists used CRISPR Cas9 DNA editing to repair a defective gene in a human embryo. Should this be allowed? Is preventing disease and disability in the children sufficient justification for changing the genetic makeup of a human being? What about “designer” children whose DNA may be changed solely to produce an athlete or supermodel body type?

What is the purpose of the Human Genome Project? Why do researchers want to know the details of the human genome?
The first attempts at gene therapy began in 1990 with the treatment of a young girl with a genetic disorder abbreviated SCID. What does SCID stand for? In the context of SCID, what does ADA stand for?
If you had the ability to do gene editing with ONE gene for the betterment of human kind, which one would you choose, and why? Assume you could either change an abnormal allele associated with a disease, such as the cystin gene associated with Cystic Fibrosis to its normal wild type, or add a pre-existing human allele to a genome.
