The Use Of CRISPR Technology - 1183 Words

In this TED talk, biologist and geneticist, Jennifer Douda, presents a way to edit our DNA with the use of CRISPR technology. This technology allows scientists to change the DNA within our cells that could ultimately allow scientists to cure various genetic disease such as sickle cell anemia, Huntington’s disease and cystic fibrosis etc. The way this technology works is that the Cas9 protein seeks foreign DNA, and precisely cuts that DNA out and eventually degrades it. After the mutated DNA is removed from the double helix, the cells detect the broken DNA double helix, and repairs it by pasting its ends together via a tiny change within the sequence of the DNA, or cells may simply introduce a new sequence of DNA at the site of the break,†¦show more content†¦Currently, CRISPR has been introduced in mice and monkeys. In mice, CRISPR was able to effectively disrupt the gene that codes for coat color. This small change in the mice genome resulted in a litter of solely bl ack pigmented mice, as opposed to a mixture of white and black mice. In monkeys, scientists are testing ways in which this technology can be introduced into an organism, as well as how to better control the reparation of DNA after it has been cut, and limit unintended outcomes. Jennifer Doudna proposed the idea that there should be a global pause in the application of this technology in human embryos until the undesirable outcomes and unknown effects have surfaced, and are carefully tested. She also acknowledged that it is irresponsible to implement the CRISPR technology in humans until its safety is validated, and all ethical concerns are put to rest. TED talks are a great way to find information on trending topics in science as well as other fields, but these presenters can present a lot of bias into their research that challenge the credibility of their work. I would say this source is not very reputable due to the fact that I do not know exactly where Jennifer Doudna got her information from. I understand that TED talks are very peculiar in who and what they allow to be presented, but bias is very easy to include in researchShow MoreRelatedThe Use Of Crispr / Cas9 Technologies1518 Words   |  7 Pages Current Research Since the implications of CRISPR/Cas9 technologies were discovered, research has mostly gone in two different directions. Bioengineers and pathologists are starting to experiment with using CRISPR as treatments to hereditary diseases with the hope that someday, they could cure certain genetic diseases. Another application currently being experimented with is using CRISPR to genetically modify organisms for various purposes. Applications for Medical Treatment and Research CurrentlyRead MoreTherapeutic Applications Of Crisp In Literature717 Words   |  3 PagesThe first mention of CRISPR in the literature was in 1987, however, it has only been in the last several years that significant headway has been made identifying potential therapeutic applications of this system. Research into this technology has been abundant in recent years, with over 4,000 publications describing CRISPR between 2007 and 2017MA2. In simple terms, CRISPR allows the scientific community to alter the DNA sequence of an organism’s genome, at an exact location, to introduce a specificRead MoreDelivery Of The Cas Components1306 Words   |  6 PagesDelivery of CRISPR-Cas Components: CRISPR systems are generally delivered in the cell using normal methods of transfection such as microinjection, gene gun, electroporation, sonoporation, and using viruses such as adenoviruses and lentiviruses. In cultured mammalian cells, researchers have used electroporation, nucleofection, and Lipofectamine mediated transfection methods to deliver vectors expressing the gene for gRNAs and Cas9 endonuclease. In cultured human and mouse cells, Lentiviral vectorsRead MoreThe Genome Editing And Crispr Technology1458 Words   |  6 PagesGenome Editing and CRISPR Technology The research surround genome editing is fairly recent but has been of great scientific discovery by correcting faulty genetic diseases. With the contemporary research regarding genome editing or genetically altering the genes of an embryo, the types of sources that embodied this research was minimal yet paramount. The amount of information gathered from online libraries and texts attained from the library the technology used for genome editing CRISPR/Cas9, it is clearRead MoreGene Review : Gene Editing1665 Words   |  7 Pages Gene editing with CRISPR-Cas9 will be the next cure for cancer, many other diseases and could change many lives. Even though this ground breaking technology has not been put to use on humans yet, when it does it will be well worth the wait. Many countries have been working on the CRISPR-Cas9 for months to allow it to be used to cure the many diseases that can not be cured with modern technology. Gene Editing is a method that can be used to change or edit the genetic code.

Utilization of this process could have the potential to revolutionise medicine due to its genome editing capabilities. CRISPR-Cas9 can act as an exceptional tool for functional genomics which can allow us to understand phenotypic and physiologicalRead MoreThe And Viruses And Their Biological Function Essay1527 Words   |  7 PagesCRISPR loci are first identified in archaea and bacteria when they systematically drew attention from scientists with their biological function to fight phages and viruses (Hsu, Lander, Zhang, 2014). Structurally, a clustered set of Cas (CRISPR-associated) genes and a unique CRISPR array constitute the CRISPR loci. The CRISPR array was further comprised of short repetitive sequence interspaced by distinctive sequences (spacers) in cor respondence with exogenous genetic bits (protospacer).

Through many advancements of technology, the CRISPR method has emerged, and it is providing the opportunity for genetically modifying the human genome to take off. However, allowing the use of the CRISPR method is not just a black and white decision. Modifying the human genome is a hot debate in the science and medical fields todays.

With the increased technology that has been introduced in the past couple of years, changing a fetus’s genes and creating â€Å"designer babies† could become a possibility for parents (Gallagher 1). When these breakthroughs were published, there was an immediate uproar about whether changing one’s baby’s genes is ethical. The events that have led to this technology, and the technology itself, are intriguing to many genetic scientists around the world.
