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

Human genetic engineering can save people's lives now and could save more in the future. According to a New Scientist article (Le Page, 2015), Layla was three months when she was diagnosed with acute lymphoblastic leukaemia, a kind of cancer in the bone marrow. She underwent other treatments like chemotherapy, but those failed so she underwent gene therapy by using the TALEN protein to edit her genes to produce a cancer fighting T cell called UCRAT19; She survived and thrived (Le Page 2015). Saving someone’s life through human genetic engineering doesn’t even have to be as complicated as altering genes. According to TIME Health (Park, 2014), Mya Burkhart was six months old when her parents started to look for a cure to her rare mutation in the gene for citrate. This mutation prevented certain parts of her from getting enough energy, causing breathing and development problems, and after having no luck with any other diagnosis, a genetic scan figured out what the issue was and gave her citrate supplements (Alice Park, 2014). Both Layla’s and Mya’s lives were saved because of human genetic engineering. Layla was cured of cancer because of human genetic engineering, which is one toughest diseases for humans to cure right now, while Layla’s cancer was cured, but Mya’s condition was only treated so maybe if human genetic engineering could continue a cure could be developed to improve her life.

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.

CRISPR stands for Clustered Regularly-Interspaced Short Palindromic Repeats, so it’s simple to see why it was abbreviated. Whilst the topic of genetic modification with humans has been relatively untouched, and in many cases unheard of, in the general public, when we learnt about genetic modification, we learnt more about the way that it works rather than how far we can go with this new technology. What can we do with this, how much can we modify our own genes and to what extent can we do so?

The current applications of CRISPR have improved thoroughly since the first days of transgenic creations, and now with the help of the previously mentioned transgenic organisms, CRISPR has been created. CRISPR is currently being used in a variety of ways, whether it be through adaptation to severe weather, or even through creating medication to cure previously incurable diseases. There are no lengths

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

Modifying genomes hasn’t been perfected, and is far too great of a risk to use on society. No one knows what could happen to the population after man starts messing with mother nature. Scientists who are trying to destroy genetic diseases could create new problems or end up killing its test subjects later down the line. The possibilities for disasters are endless. People also claim that modifying humans is the fastest and most efficient way to getting rid of physical and mental health problems, but according to Molecular biologist Ellen Jorgensen, Using CRISPR isn’t what people see it to be. Ellen explains that using CRISPR is not actually easy at all. To use the technology, damaging the gene is crucial. Once the gene is damaged, and the cells start to repair, scientists can then manipulate the cells to repair the way they want it to, and not naturally. This is a complicated process, and it not in any way

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.

Knowing how CRISPR works we can go from here. In the future we can use CRISPR for treating disease or editing the genes of human embryos. The main focus for the future, though on CRISPR is the ability

Genome editing, or gene editing, is a type of genetic engineering in which DNA is inserted, deleted or replaced in the genome of a living organism using engineering ucleasus, or “molecular scissors” in the layman's terms. The technology at head of this procedure is the CRISPR-Cas9,the most versatile and precise method of gene editing and also is what made gene editing the hot topic it is in the medical world. As a result, of this breakthrough medical scientists have the ability to cure sickness, by eliminating genes that cause disease doctors can treat a wide range of illness

Even though it was discovered in 1987 by a research team at Osaka University, the true power of CRISPR, which functions as an adaptive bacteria immune defense, was not realized until the completion of the Human Genome Project in the early 2000’s (Carroll and Zhou 63-64). There are only two components of CRISPR, a guide RNA sequence (gRNA) and a Cas9 endonuclease protein. When the gRNA binds to its matching template DNA sequence, the Cas9 protein cuts the template DNA sequence resulting in the inactivation of that specific gene (Hille and Charpentier 3). In addition, a mutant gene can be replaced by adding another piece of DNA with the desired sequence, which will bind to the cut DNA template strand and become incorporated into the host

Have you ever thought about being able to pick what hair color your baby has before he or she is born? How about their eye color, their intelligence level, or their looks? What if I told you that soon this could be a possibility thanks to Clustered Regularly Interspaced Short Palindromic Repeats, or CRISPR-Cas9. CRISPR-Cas9 is a technology that can edit DNA. It is a type of germ-line engineering that is a “search-and replace tool” that is able to alter DNA, even down to a very single letter. According to Technologyreview.com, “The CRISPR system includes a gene-snipping enzyme and a guide molecule that can be programmed to target unique combinations of the DNA letters, A, G, C, and T; get these ingredients into a cell and they

The molecule which we know as CRISPR was discovered in initially found in a species of E. coli. But since it’s identification scientists have found the molecule in some 90% of archaea and most bacteria (Horvath and Barrangou 2010). In the microbes that it is found, CRISPR has a more specific purpose than gene modification. CRISPR, and the associated genes are part essential of protection and

One of the main uses of CRISPR-Cas9 is to generate knock-out cells or animals, however modifications can be made to the Cas9 enzyme to selectively activate or repress target genes or purify specific regions of DNA. Before discussing how CRISPR works, it is important to understand its fundamental parts. There are two components of CRISPR, one being a “guide” RNA (gRNA) and the other being a non-specific CRSIPR-associated endonuclease, which is Cas9. The gRNA is synthetic RNA made up of a “scaffold” sequence for the Cas9-binding and a user-made nucleotide “spacer” sequence. The genomic DNA being addressed can be any 20-nucleotide DNA sequence as long as it meets certain conditions. This includes being unique compared to the rest of the genome and the target is present upstream of a Protospacer Adjacent Motif, or PAM. (“CRISPR/Cas9 Guide”, n.d.).

CRISPR is a new breakthrough, so it has had limited human application. This approach has been used on animals, particularly infected with the HIV virus. Scientists at Temple University used CRISPR to cut the HIV DNA out of the host cell genome (Park 2016). The HIV virus works by injecting RNA into a host cell. The RNA then changes to DNA using an enzyme called Reverse Transcriptase. The DNA is then incorporated into the host cell’s genome, allowing the HIV virus to be made and assembled in the cell. Once the virus is made, the new virus buds out of the cell and spreads through the body. This knowledge led to Kamel Khalili, a director at Temple University to use CRISPR to cut the viral DNA out of the host cell’s genome (Park 2016). The success of CRISPR in animals
