Gen(e)iuses at Work
Genetic Engineers carry out work that may result in breakthroughs spanning across a broad cross-section of life on earth.
Gene Therapy
Gene therapy involves inserting a gene into a patient’s cells to treat or prevent disease instead of using drugs or surgery. Although still experimental, gene therapy aims to target the root cause of illness, such as gene transfer into the individual cell types of the complex lung structure in cystic fibrosis patients. It has the potential to save a patient from a lifetime of complicated treatments, all the while suffering a debilitating medical condition.
Genome Editing
The invention of powerful new genome-editing tools means that researchers can now make precise changes to genetic material and thereby consider correcting faulty DNA in human sperm, eggs, and embryos.
Virus Vectors
Genetic Engineers use carriers called vectors to transmit genetically modified cells during gene therapy. The most popular vectors are viruses that have been modified so that they do not harm the individual. Research to find viruses that can serve as the most beneficent vectors is one of the most crucial tasks in the field.
Combating Hunger
Genetic Engineers work with agricultural scientists to develop crops resistant to diseases, pests, drought, and weeds. Their efforts help reduce the number of harmful pesticides needed in growing crops and produce food free of allergens or toxins. They use biotechnology to increase the nutritional value of crops and the quality of seed stock.
Animal Science
Genetic Engineers strive to increase livestock productivity, improve the health of animals, and reduce the environmental impact of agricultural production. They engage in the safe genetic engineering of animals for research.
Clean the Environment
Genetic Engineers help scientists develop ways to clean up pollution. For instance, bioremediation enables the clean-up of chemicals, including paint in landfills or oil, accidentally spilled into soil or water. It empowers microbes to break down toxic substances into simpler substances that are less harmful to the environment.
Genetic Engineers introduce pollution-fighting genes from another species into a microbe to enhance its pollution-fighting skills or engineer the organism’s existing genes to make it more effective.
An Ongoing Debate
The more we learn about genetics, the more complicated the interactions between genes and the environment — which produces the organism’s phenotype — appear. It is one thing to cut and paste DNA, but it is another to know what the result will be, mainly because modifications to one part of the genome can have unexpected effects elsewhere.
Some enhancements can improve the human condition as we know it, and some have the potential to wreak havoc on our lives and social structure. Anyone who has a position on enhancement has not thought deeply enough on the question.
Genetic Engineers can expect to answer regulatory, legal, and ethical questions correctly only on a category-by-category basis.
