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?

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?
I believe that there are many good things that can come out of people getting to design their baby’s genetic material. But there are also many bad things as well. From the article by Bio medical about the pros and cons of having a designer baby it states that a pro is that this type of engineering can “ might help prevent genetic diseases such as Alzheimer’s, Huntington’s Disease, down syndrome, Spinal Muscular Atrophy, and many others”. I think that it is great that we could get rid of Alzheimer’s due to how destructive it can be to the people that suffer it. But I think the other diseases that it can eliminate is horrible due to them making our world a more unique place such as people with autism, Down syndrome. By doing this it could eliminate the whole population of people with disabilities community and make everyone “normal”. Another bad that I found in the article Ethics of designer babies which states that a major flaw for these babies is “designer baby technologies suggest…

Others have argued that no genome editing should be carried out on human embryos. Present arguments for and against using genome editing on human embryos.arrow_forward

Gene therapy is dedicated to correcting genetic defects by replacing mutated genes with wildtype versions. This can include complete removal and introduction of a working copy of the entire gene (using knock-outs and knock-ins) or removal of only the actual mutated nucleotide. Sickle Cell Disease is an example of a recessive disorder based on a single-point mutation: GAG becomes GTG, which encodes a new amino acid. One would only need to replace a single base to correct the disorder making it very attractive to gene therapy researchers. The mutant sickle cell allele is called HbS (for sickled hemoglobin) while the wt allele is HbA. Pretend that Arcel Kasongo, a masters student from Cambridge, is studying for an oral exam on gene therapy, and has an especial interest in the disorder since he comes from the Democratic Republic of Congo…arrow_forward

The inserted gene is usually from another species. The purpose of this manipulation is to give the target organism and its offspring a new trait that improves it in some way. The improvement might, for example, give the organism higher vitamin content. The process is called genetic engineering. 1. What are genetically modified organisms? 2.
