Ever since the structure of DNA was discovered in 1953, there have been various advancements.(1) This includes a powerful tool that allows us to modify the genes of human embryos, called CRISPR. Currently it is not legal to modify an embryo and let it develop, but should we ever? On December 1 through 3, 2015, an International Summit on Human Gene Editing took place in Washington, D.C. to discuss what should be done with the new biotechnology.(1) There was much controversy about this, both morally and scientifically. If it were successful, then there would be many benefits. However, there are also equally great drawbacks whether it succeeds, or not. Due to this, arguments for the development of genetically modified embryos face opponents arguing against it.

First, to look at genetically modified embryos in a positive light, think about all the advantages it could bring. According to research done by National Geographic writer, John Harris, about 7.9 million children are born with genetic defects every year.(5) These defects could result in Huntington’s disease and …show more content…

Published in 2012, this technique allows for the rapid alteration of the DNA of nearly any organism – including a human.(1) Essentially, it uses bacterial enzymes to cut genomes at specified spots; replacement genetic material can then be inserted into the genome.(1) It’s cheap, quick, and easy to use! For many parents whose children suffer from genetic diseases, germline editing is a compelling chance. In addition, we could enhance our DNA, making us immune to deadly, incurable infections, including HIV.(1) Finally, beyond preventing diseases, the ability to edit embryos opens up an exciting new means for understanding our basic biology.(3) For example, it could be used to study how a fertilized egg develops into a baby, as STAT
