Using Frame Shift As A Platform

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

Humans have been genetically engineering organisms for nearly 10,000 years using traditional methods of modification—among these methods include selective breeding and crossbreeding. Though effective, these methods were unreliable and were only able to change certain traits. A lack of control over our genetic material proved to be a clear hindrance to our species; when harnessed, advancements in other fields of knowledge would be immeasurable. Once seen as an impossible task, scientists have been able to exploit genes and take control of them. CRISPR-Cas9 is a system that allows scientists to cleave off sections of DNA and artificially modify them by inserting a mutation into the place of the old DNA. This is exceptionally precise, whilst

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

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.

For many years biomedical researchers like myself have been trying to create more proactive ways to amend the genome for living cells. In more recent fieldwork studies there has been a new state of the art instrument based on bacterial CRISP in close works with protein 9 often referred to as CAS9 from the streptococcus progenies have possibly unlocked new data. The CRISP/CAS9 tries to manipulate the function of the gene using homologous recombination and RNA interference, but is set back because it can only provide short term restriction of the genes function and it’s iffy off- target effects.

Genome editing is still relatively new in the science world. It was only fairly recently that we gained the first ability to fix our DNA (Rajan). Genome editing is changing the DNA, which gives us the ability to change it for the better – which is not an easy thing to do (What Is Genome Editing?). In order to change the DNA, clustered regularly interspaced short palindromic repeats (CRISPR) are manipulated to improve the DNA (Hornblower, Reis, Robb, and Tzertzinis). A fracture is made in the DNA to modify it, in order to adjust the DNA to try to rid it of genetic diseases and abnormalities (What Is Genome Editing?). Then, a new sequence can be added into the existing DNA and be repaired (What Is Genome Editing?). This is the basic idea of the difficult genome editing. While complicated, once more progress is made and it becomes more successful, this process could work on a variety of diseases (What Is Genome Editing?).

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.

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.

Duchenne Muscular Dystrophy (DMD) is a lethal genetic X-linked disease results from the mutation in the reading frame of the dystrophin protein, and it affects mostly boys in their muscle and cardiopulmonary function. Although there are no effective treatments to cure DMD patients right now, scientists consistently explore more methods to come up with the practical treatments. One of the most popular and valid approaches is a gene-editing therapeutic method – CRISPR/Cas9 Genome Editing. It adapts from the natural systems in bacteria, and it can generate targeted gene modifications to target specific DNA sequence. Then it introduces shifts within exons to restore the reading frame, so it can express a partial functional dystrophin protein.

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.

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.

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.

Granted there have been other gene editing techniques used before, but by far CRISPR has been reported to have the most potential to revolutionize different areas where the method is applicable. The fields that researchers believe these modification resources will be the most beneficial, include but are not limited to medicine for curing and preventing diseases, creating socially ideal children, and perhaps aiding in the decrease of world hunger. While these goals do seem quite optimistical, scientists have high hopes for what CRISPR will be able to accomplish with time. Currently the system is just now being tested out on living organisms, with the ambition of figuring ways to genetically terminate diseases (2).
