CRISPR: The Future of Gene Editing, What Lies Ahead?

CRISPR is a repetitive DNA sequence found in bacterias. It is perhaps the biggest breakthrough in science and genome editing in decades, where CRISPR allows for a specific DNA sequence to be removed and then replaced or supplemented with a different DNA fragment. With the use of genome editing technology, it is possible to change genes and give humans and animals new physical or genetic traits. Increased height, change in eye color or immunity to diseases, the possibilities are endless but not without certain limitations, as the future of genome editing is yet to be tested by ethical constraints and scientific limits.

What is Germline Editing and its Restrictions?

It is not only possible to alter animals, human or crop’s DNA but also for gametes and early embryos, this is known as Germline Editing. Future generations will be affected by changes made to germline cells, which is still a touchy subject with regards to its societal acceptance. Theoretically, this may be utilized to improve the physical limitations of future generations, giving them a longer life expectancy. Many countries have strict policies regarding Germline Editing and its implications and many do not fund the research for editing of human embryos. But one thing is for certain: instead of relying on natural selection to survive, humans now have the ability to adapt and become better than ever before.
