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

During January of 2013, scientists based at the Broad Institute of MIT and Harvard were able to demonstrate fixed change in human and animal cells using CRISPR-Cas9. This marked a turning point in genetic advancement—though CRISPR was far from mastered, its potential was beginning to show.

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

The Gene Hackers published by the New Yorker’s Michael Specter talks about a breakthrough technology that could allow for the creation of genetically modified humans- “humans 2.0” as he calls it. This new technology could also be the cure for many genetic disorders like Alzheimer’s, Huntington’s etc. as it would allow scientist the ease of genetically identifying and editing specific genes responsible for these genetic abnormalities. This exciting new technology will be known as Clustered Regularly Interspaced Short Palindromic Repeats associated protein 9 or CRISPR-Cas 9 for short.

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

CRISPR Cas-9 is a system that changes genes and shows a further promise for treatment for Duchenne Muscular Dystrophy (DMD). Doing this will hopefully avoid ethical dilemmas. DMD effects nearly 1 in 5,600-7,700 people between the ages of 5 and 24 for males in the U. S. CRISPR stands for “Clustered Regularly Interspaced Short Palindromic Repeats”. These are DNA segments found in microorganisms that repeat itself in open spaces. CRISPR attacks any virus that comes into your body and cuts the strand of virus on the DNA out. Researchers have tried to cure DMD in mice by getting therapy through the back of the eye, one of the ways CRISPR therapy works, which seems to work best.

CRISPR is a technology that allows DNA sequence to be altered in a precised manner in order to avoid genetic mutations that may lead to different diseases. It works by the action of the protein called Cas9 that acts as a molecular scalpel. Cas9 has the ability to detect which parts of the DNA are defective. After it determines where that part is, it attaches itself to it and after a series of chemical reactions, it cuts it right at the spot of the malfunctioned DNA. Sometimes, a new DNA can be attached to it so that the cell can work properly again.

She reported that this technology is widely used in labs around the world today, and it is easily accessible using a $130-CRISPR

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.

Genetic diseases and illnesses have been of much concern for many years, leaving many deceased or with a poor quality of life. Due to the implication of modern medicine and other techniques used for treatments, mortality rates have decreased and the average life expectancy has increased. Unfortunately, every individual responds differently to the type of treatment they need, which is why the implication of personalized medicine is forthcoming. A certain technique that has been distinguished and commended by researchers today is known as clustered regulatory interspaced short palindromic repeats, or CRISPR. CRISPR is associated with Cas9, and it is a popular genome editing technique which can be programmed to target specific areas of DNA and

Imagine a world where we can control genetics. What if we had the opportunity to eliminate all genetic diseases in just a few steps. Imagine a society where anyone could flip through a catalog to shop for traits to “design” their child. This may seem a little far fetched, however this imagined world may soon become possible through the rapid advancing development of genetic engineering. New and advanced technology has finally made it possible to access and hack the human genome. New gene editing technology called CRISPR Cas-9 has completely transformed the biomedical field. CRISPR Cas-9 is cheap, precise, efficient and ultimately works on all living organisms. Advanced genetic technology that have allowed us to genetically modify our food and clone sheep, may one day give parents the option to modify their own children. However the idea of one day creating “designer babies” sparks great controversy.

The process used to modify genes is called CRISPR/Cas9. It was discovered in china in 2013; before CRISPR, scientist would

    Through recombinant DNA techniques, scientists have already experimented with bacteria and copied their cellular system that allows them to defend themselves from viruses in order to create a new restriction enzyme called Cas9, which then gets bound to an RNA guide strand. This new enzyme introduces new genetic material into the human genome as DNA replicates. This method will be useful for families members who carry harmful recessive alleles. Their babies could inherit the genetic disorder, but with recombinant DNA techniques, the harmful gene or genes could easily be replaced with a functional gene. Lauren Friedman, Senior editor for
