CRISPR/Cas9 changed genetic engineering forever by editing in the DNA directly and finally getting it right. Aside from all the hubris that it has generated on how it’s going to revolutionize human medicine, uses of CRISPR are not limited to non-human genes. From animal and plant breeding to nature reserve management and industrial biotech to even eradicating infectious diseases, CRISPR is writing the book in an infinite number of scientific fields.
Description of CRISPR/Cas
CRISPR stands for the bacterium’s defense system through which bacteria are able to cut their way to resistance against virus infections. Scientists used the system to invent CRISPR/Cas9, the science by which scientists have been editing genes. Cas9 is an enzyme that constitutes the molecular scissors that snip the DNA at some exact site for the scientists to remove, replace, or insert genetic code with unprecedented accuracy.
Application of CRISPR in Agriculture
The field with the highest potential for applying CRISPR is agriculture. The population of the world is increasing, and the world is also gaining more problems, and therefore researchers are trying to develop healthier, sustainable, and environmentally friendly crops with the help of CRISPR.
1. Enhanced Crop Yield and Resistance
CRISPR has also been employed to make crops more resistant to drought, insects, and disease and to provide more nutrients. Wheat, maize, and rice genes, for instance, can be genetically disease-resistant with the aim of minimizing chemical pesticide use.
2. Enhanced Nutritional Content
Scientists apply CRISPR technology to improve the nutritional value of foods nowadays. CRISPR, for instance, is utilized in production of improved beta-carotene content in rice for generating “Golden Rice,” the first-morning breakfast cereal that was made with a mission to eradicate Third World vitamin A deficiency. Similarly, the same applies to vitamin and mineral supplementation of other staple food crops.
3.Food Loss Reduction
CRISPR is also employed for providing fruits and vegetables with longer life cycles so that they will not rot or bloat brown. Mushroom tissues are genetically engineered so that mushroom tissues will not become brown. These systems minimize wastage along value chains by humongous gigantic margins.
CRISPR in Livestock and Aquaculture
CRISPR technology is also transforming animal husbandry in the form of better animal health, reduced environmental footprint, and more effective food production.
1.Disease-Resistant Livestock
Scientists have already employed CRISPR to engineer pigs that are resistant to PRRS, a disease costing the livestock sector billions of dollars every year. The technologies are also being applied to screen cows and chickens for the purpose of immunizing them against bacterial and viral disease.
2.Enhancing the quality of Meat
Gene editing has also been employed to enhance the quality of the beef by making the animals gain muscle but not fat. Gene editing has also been employed to genetically rear cows in an attempt to make them muscular and hence produce healthier leaner beef.
3.Rearing fish for aquaculture in an ecologically sustainable way
Fish farming or aquaculture is also beset by disease epidemic and the environment. CRISPR is enabling production of disease-free fish and limiting use of antibiotics to offer more sustainable seafood.
Environmental Conservation and Conservation of Biodiversity
Conservation also depends on CRISPR and simple regulation of invasive species, conservation of endangered species, and mending the ecosystem.
1.Regulation of Invasive Species
Invasive species overwhelm ecosystem operation and cause damage to native biodiversity. Researchers are using CRISPR technology to design gene drives—gene components inherited by a species generation after generation and transmitting through a population—to control invasive pests such as malaria-inflicting mosquitoes or invasive rodents consuming island ecosystem health.
2.Bringing Back Endangered and Extinct Species
CRISPR is studied as a conservation tool, i.e., to bring back extinct life or save dangerous life. Scientists are trying to edit the genome of the Asian elephant in a manner that it can be implanted with genes of woolly mammoths inside it so that they won’t die due to low temperatures and can bring back devastated habitats again.
3.PESTERING Plastic Pollution
CRISPR also finds applications in industrial biotech for the bioengineering of microbes into strong plastic breakers that would be useful in the regulation of the plastic litter menace across the globe. Genetically modified microbes would prove to be priceless assets while conducting the bioremediation process, breaking down toxic poisons from water and the environment.
CRISPR in Industrial Biotechnology and Biofuels
Apart from agriculture and medicine, CRISPR is revolutionizing industrial biotech to create genetically modified microbes for sustainable production to be attained.
1.Massive Production of Biofuels
CRISPR is employed in the engineering of algae and bacteria to generate biofuels. Researchers are genetically engineering the genes to cause the algae to increase the production of lipids for use in manufacturing biofuels to be used as a renewable energy source.
2.Synthetic Biology and Biomanufacturing
CRISPR is applied to bioengineer yeast and bacteria to engineer useful products like medicine, bioplastic, and even meat grown in the lab. It makes metabolics cheaper and sustainable by streamlining metabolism.
ERadicating Infectious Diseases using CRISPR
Accuracy of power to edit with CRISPR potentially understand infectious disease in animals, plants, and human life.
1.Gene Drives for Malaria
Researchers are using CRISPR to engineer gene therapeutics to spread genetic alteration across insect populations so that they can no longer pass on malaria. It holds the potential to be able to make a considerable contribution towards halting malaria transmission in disease-endemic regions.
2.CRISPR-Based Antiviral Discovery
Scientists are developing CRISPR-based treatments to destroy and eliminate viral DNA in viral infections such as HIV, herpes, and even COVID-19. CRISPR can even cure viral diseases that are otherwise incurable.
3.Antibiotic Resistance Breakthrough
Though the apparently infinite increase in antibiotic resistance among bacteria is a persistent issue, CRISPR has also been suggested as a means of killing resistant strains of bacteria independently without killing other bacteria and thus potentially provides us with a new weapon in the fight against superbugs.
Ethical Considerations and Challenges
Though the world will be revolutionized through CRISPR technology, regulation and ethics are raising an alarm bell. Editing plants and animals, potentially unintended ecological consequences, and gene drives in the wild are some of the concerns to meet with utmost caution.
1.Ecological Risks
Genetically modified organisms put into the environment will cause harm in the act of uncontrolled mutation or upon invading ecosystems. Control must be exercised so appropriate care can be given.
2.Public Perception and Acceptance
There is going to be irretrievable public distrust that will accompany gene editing in animals and food. Public education of the safety and usefulness of food by CRISPR modification must be accomplished so that it can generate mass acceptances.
3.Regulation
Gene editing is treated differently worldwide. There are nations that have welcomed the use of CRISPR-edited crops and others that have not accepted it. There has to be some kind of global standard in maintaining it so that ethical application of CRISPR on non-humans is ensured.
Conclusion
CRISPR/Cas9 technology must be taken extremely seriously outside of human genetics. Its applications are manifold, ranging from conservation biology and food security and disease control and renewable energy. Science has delivered some of humanity’s most basic questions on the platform of CRISPR. Ethics and law must keep its development in check so that such new technologies arrive responsibly for all of humanity and earth.
