One of the biggest ethical arguments against gene editing is that, technology has brought up stakeholders that are among the medical community and patients, since they are using our genes and changing them to creating a longer life. About 10 years ago, biologists discovered enzymes called zinc finger nucleases that were one way to edit genomes. Treat PTSD. The embryo then repaired the cut in the sperm’s genetic material by copying the egg’s healthy gene, leaving the embryo free of a genetic disease that would otherwise be passed down by the father. The ethical implications of gene editing are quite proportionate. If it does not match, then Cas closes its DNA loop that shows the displaced DNA strand and continues searching for its matching DNA (Doudna and Charpentier, 2014). Biology The Basic Concept Go ahead: take a walk on the wild side. The CRISPR/Cas9 technology has been a revolutionary breakthrough in the field of Genetic modification. Genome editing also holds a considerable impact on the field of food improvements. In addition certain nucleotide triplets could not be targeted, and interactions within a zinc finger array could reduce specificity (Moon and Kim ,2016). There are concerns about this advancement, Michael Specter in his essay “The Gene Hackers” and Atul Gawande in his essay “Slow Ideas” both delve into scientific topics.
