CRISPR-Cas9 Essay

CRISPR is a new gene-modifying tool that has the potential to treat numerous medical conditions by editing genes that are responsible for certain diseases. This technology is based on the ability of bacteria to destroy the DNA of invading viruses. Studies have suggested that this new technology can be applied to human cells, although the idea of chopping up regions of the human genome can be unethical and could even be harmful. In order for the treatment to be administered to a patient, a small piece of RNA and an enzyme that makes a cut in the DNA are delivered to the cells. A biotechnology company, known as Editas Medicine, located in Cambridge, MA, is already designing treatments for conditions of the blood and the eye using CRISPR. For

magine, 20 years from now, sitting in a cold doctor's office deciding the genes of your unborn baby, what color hair, eyes, speed of metabolism, height would you even know what to pick? Impossible you might say but in this day and age technology is growing ever so rapidly that picking the genetic makeup of your baby is closer than you might think. The technology is called CRISPR. This technology doesn't only have the ability to change physical traits, but genetic traits specifically genetic abnormalities and diseases. 20 years ago, no one would have ever thought we would have the answer to, in theory, cure every genetic disease from sickle cell anemia to cystic fibrosis. However, with great scientific breakthroughs comes questioning and

Genome editing is a huge leap forward in science and medicine. Because of recent advances in technology, the study of genes and induced ‘point’ mutations have led to the discovery and advancement of methods previously used in order to mutate genes. The development of Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPRs) and CRISPR associated system 9 protein (Cas9) technology is a hugely significant leap forward as this is a tool that could potentially be used for the research into and hopefully the treatment of a range of medical conditions that are genetically related. Cystic fibrosis (Schwank, G. et al, 2013), haemophilia and sickle cell disease are an example of some of the conditions that have the

Mullis came to light. This technology seemed to to hold a promise that it would end human suffering, that it would be the road to a perfect world, where diseases were no longer a threat and pesticides would become an archaic method of the past. This new technology was called PCR, and it was the earliest form of gene editing. Fast forward to today, where another great leap in the science of gene editing has just occurred - one that might be exactly what everyone thought PCR would turn into. This leap has been dubbed CRISPR, and its capabilities make PCR look like, well, nothing. CRISPR uses a device originally found in bacteria called CAS-9 to precisely snip a targeted area of an organism's genome and replace it with the correct gene. CRISPR is by all accounts an amazing technology, but there are some who think it should not be used. CRISPR has

With modern technology comes the breakthrough of the decade by altering the human genes. This altering gene invention is called CRISPR/Cas9. However, this invention in the beginning stages of altering genes, began with rats until perfection. The process began early with the embryo stages to edit the genes. With the introduction of CRISPR surrounds a lot of controversy. Some people believe editing genes is playing with the hands of God and refuse to believe in CRISPR. With the article, “Let’s Hit Pause Before Altering Humankind”, by David Baltimore believes CRISPR is a tool with no good intentions. With this information the article should not be published with being against CRISPR.

CRISPR has been garnishing a lot of media attention recently and it is not just popular among the scientific community but also the general public. Several online news outlets and scientific journals have been talking about the significance CRISPR-Cas could have for the field of genetics and science as a whole. I even came across a Youtube video from The Verge, a tech channel that normally does reviews on new smartphones and laptops talking about CRISPR [15]. So why is CRISPR gaining so much attention both from the scientific community and the general public? The answer lies in the potential this technology possesses.

The removal of malaria from mosquitos hasn’t come without negative opinions though. Some scientists such as Renee Wegrzyn argue that “If we introduce a gene drive into the environment, then how can we reverse that tool if it has an unintended consequence? Can we demonstrate that we can turn those gene drives off at will?” This argument is valid, as if the alteration doesn’t work, and the CRISPR, gene

CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeat, referring to the repeating DNA sequences found in the genomes of microorganisms. CRISPR technology allows scientists to make precise changes in genes by splicing and replacing these DNA sequences with new ones. Through these changes, the biology of the cell is altered and possibly affects the health of an organism. The possibilities are endless as this offers opportunities in curing deadly diseases, modifying genes, and changing humanity as we know it. Although bioengineering has been around since the 1960s, CRISPR is significant because of the comparative low costs and the ease of the procedure to

There are other types of gene editing out there but research shows us that CRISPR is fast, precise, and simple. Researchers are developing a way for CRISPR therapy to help with Alzheimer’s all the way to HIV. There are two categories the researchers and people have put CRISPR in: practical and philosophical. The researchers say that the immediate barrier is practical. During the tests, CRISPR has found targets in other parts of the DNA that need fixing other than the intended part of the DNA. Because of this, it may take at least a generation to ensure that it is safe. Some people oppose CRISPR because the oppositionists say it lets people play god but getting medicine every time you get sick with the same thing obscures the natural order of things. The opportunities are getting pushed ahead for treating cancer, childhood diseases that are genetic, and how to understand diabetes better. The one question some people have is whether it’s right to edit genes that are

The author gives a brief history of past genome editing but thoroughly explains the history and mechanism of the CRISPR technology. She elaborates on how the technology has already been used to cure diseases and speculates on its future uses and regulation.

Due to CRISPR-Cas9’s low cost, global scientific research on genetic editing has flourished. The power of CRISPR “is so easily accessible by labs — you don 't need a very expensive piece of equipment and people don 't need to get many years of training to do this” (Ledford). Because of this, CRISPR technology has spread to labs across the globe. There are two main economic

In “Life the Remix,” Alice Park discusses the impact and influence CRISPR has on science as well as its potential and risks. CRISPR—“clustered regularly interspaced short palindromic repeats”—is a technique to alter DNA, virtually for anything involving DNA. Although there have been attempts to edit DNA, none were as cheap and simple as CRISPR. This technique, which is based on the immune system of a bacetria, revolutionizes genetics after the subsequent discoveries of the molecular scissors enzyme: Cas9 and a method to efficiently and accurately edit human DNA using CRISPR, explains Park.

And one of the top factors in determining the viability of genetic engineering is its accuracy. In an article reported by the Interdisciplinary Center for Studies on Bioethics at the University of Chile, it was found that CRISPR has “a high frequency of off target effects…in human cells” (Rodriguez). With a high threshold for error, CRISPR does not appear to be reliable yet, at least to researchers at the University of Chile. Ethically, this raises concerns about CRISPR being an option for usage in people due to its potential risks. Genetic engineering is far more complex than any other type of medical treatment out there, so if any type of error were to occur, it would be extremely difficult to fix. Sharon Begley, a journalist for STAT news who interviewed doctors from Massachusetts General Hospital, reported that “one concern about off-target effects is that genome-editing might disable a tumor-suppressor gene or activate a cancer-causing one” (Begley). This concern was later found to be true in a separate study performed on mice by a post-doctoral colleague of UC Berkeley’s Jennifer Doudna, where CRISPR “gave rise to mutations, creating a model for human lung cancer” (Bioethics). This study provides cold-hard evidence for the journalist’s claim that even the slightest mutation can lead to cancer.

Every few years, advancements in technology alter the way scientists do their work. Recently CRISPR-Cas9, a RNA useful for working organisms in the animal kingdom has proven itself beneficial on a gene-editing platform. After performing many abortive attempts to manipulate gene function, including homologous recombination and RNA interference, scientists have finally had a breakthrough with CRISPR-Cas9.

An idea that once seemed like mere science fiction is now, ever closer to becoming a reality thanks to advances in genetics, and the development of a gene editing technology called Crispr-Cas9, in 2012, which uses natural enzymes to target and snip genes
