Does Gene Editing Make Mankind Better?

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?).

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

All we need to do it change one letter in the genetic code. For example, in the article, “In Praise of Designer Babies”, it states, “‘It would be against nature to treat your child's illness.’ So why is it obvious that we should treat the illness after the child is born, but not prevent the illness beforehand?” It would be silly of us if we did not treat our children if we knew they had a fatal illness. It is superior to help them while they are in the mother, and not watch them suffer as they grow. We might even be able to save countless of kids everywhere, by just changing one adenine, a nitrogen base, even adding or taking away a code. For example, when a child is born with down syndrome will have an extra chromosome or a chromosome with an extra part. We can get into the DNA and delete that extra chromosome to help heal the child. Another instance is, in the same article, text, it says, “Imagine you knew that you carried a gene for a debilitating illness. But, doctors could go into your egg (or your spouse's) and remove that gene…” Just imagine all of the healthy kids that will be able to enjoy their life relating to normal children and being able to do normal activities. Kids can be ecstatic everyday and their overall health all over the world might even improve by so much just by using genetics. Another example is, from the article, “Will Gene Editing Allow Us to Rid the World of Diseases”, it

I found Weintraub’s article to be the most down to earth and approachable when it comes to the topic of Gene editing. In the article, she mentions several reasons why gene editing can be beneficial including stopping progressive diseases, such as dementia, completely in their tracks. Weintraub even suggests that gene editing could be used to save certain animals that are facing extinction due to genetic abnormalities or diseases. On the flipside, she brings up a very interesting point about how some parents may not want to use gene editing to heal their children, but rather to “improve” them by altering their genes to make them taller, more athletic, skinnier, etc. Weintraub also worries that utilizing gene editing this manner might end up

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).

It seems the future of this is now. “The science making human genetic engineering possible already exists and is being carried out, albeit in its nascent form, in labs and clinics around the world”(Metzl,2015). The early stages of doing this have started. For now it is just screening early stage embryos during vitro fertilization to find certain diseases that this baby may get (Metzl 2015). This is the first step in changing our genetics. This is a tricky one because it is helping someone, but what we don’t know is what damage that help maybe doing to them in other areas even though they can get rid of that particular disease. 80 percent of the medical school students were against genetic engineering that gives children enhanced athletic,

One reason it should be allowed is it can prevent genetic diseases. For example, Fredrik Lanner, the lead scientist on the DNA editing in Sweden states, “if we can understand the early cells of this embryo it will help us prevent diseases like Parkinson's or other genetic diseases”(Lanner). This quote shows the scientific

A simple but effective method is correctly designing gRNAs. Ideally, the target sequence must be a unique and nearly perfect homology to the gRNA with as little to no homology at other points within the gene sequence. Another potential strategy involves reducing the concentration of gRNA and Cas9 that are expressed in cells. However, this strategy is considered inconclusive due to inconsistent reporting. Some cell lines showed a large decrease in rates of off-target binding while others showed no effect. An increasingly promising method for improving specificity involves using a mutated nickase version of the Cas9 enzyme. This modified version contains only one catatylic domain and is used as a single nickase system capable of cutting a single strand of DNA. This results in a “nick” or single stand break rather then a DSB and is repaired by HDR. To further reduce the risk of off target binding, a double or dual nickase CRISPR system can be implemented. This system uses two nickases which bind to opposite strands of the target gene, generating a DSB. This system closely resembles the Fokl enzyme activation used in TALEN, in that off target effects are reduced because the probability of two off target nicks within the same region is very unlikely. When the DSB is made, activation of NHEJ is initiated; to further increase specificity and reduce off-target effects, the HDR mediated editing is advised for both nickase

Gene editing is a type of genetic engineering in which DNA is inserted, replaced or removed from the Genome or the genetic material of an organism. This treatment saved the life of one year old Layla. She was diagnosed with Leukemia and after several failed treatments, her parents turned to gene editing. Layla’s doctors performed experimental gene therapy on her, they inserted immune cells from a healthy donor into her body. The immune cells fought off the cancerous cells in her marrow.She is an example of someone’s life that was saved by gene editing.Due to the publicity this story has gotten more patients have the option of pursuing gene editing in hopes for a cure.

CRISPR is an acronym for Clustered Regularly Interspaced Short Palindromic Repeat. This name refers to the unique organization of short, partially palindromic repeated DNA sequences found in the genomes of bacteria and other microorganisms. In 2014, rumors intensified about researchers in the US and China working on human embryos with the inexpensive, easy-to-use gene-editing tool CRISPR. In April 2015, a research team at Sun Yat-sen University in China published a report of an experiment in which they used CRISPR to edit a gene associated with the blood disease beta- thalassemia in non-viable human embryos (Center for Genetics and Society). While CRISPR is cheap and easy to use, many ethical questions surround it. Ethical questions surrounding CRISPR’s human applications are not limited to altering embryos. Gene-editing treatments could spur gene-editing enhancements to give people stronger muscles, quicker growth spurts or greater intelligence, affirms journalist David Wahlberg of the Wisconsin State Journal. Equally important is TALENs, which works similar to CRISPR. TALENs is considered being used in the future within the medical careers. Here’s how it might work in the future, explains the MIT Technology Review. First doctors would remove some of the patient’s own bone marrow cells. Then, these cells would be handed to scientists so they could be treated with TALENs in the lab. Scientists would make sure that the damaged gene is fixed and then hand the fixed cells back to the doctor so they could be put back into the

The process of alteration of human DNA or genetic engineering is the process of manually adding DNA to an organism. The goal for this is to add one or more traits to an organism that does not have those traits. Also if there are traits that are not wanted in an organism those traits could get removed. A scientist would physically remove a gene from an organism and insert it into another, giving it the ability to use that trait to encode by a

    I believe editing embryo DNA is a good thing. If we can genetically modified babies in order to make mankind better, I say go for it. A world without disease is a world many of us would want to live in. I would like to live in a world where people get sick less often. If somehow we are able to prevent cancer or any life treating disease we would be able to save so many lives. Not just that, but help expand our lifespan. I know for a fact that life is too short and there isn’t enough time in the world. Preventing diseases, expanding our life and living care free. I say editing human embryo DNA is worth the risk

Although the idea of editing genes has been around for quite a while now, genome editing using CRISPR does this cheaper, quicker, with less error than ever before and can target very specific areas of the genome to change. CRISPR may be able to alter genetic defects in a person’s genome and therefore cure many hereditary illnesses like cystic fibrosis. The concern with genome editing in the future is that if scientists can eliminate genetic defects in an egg or embryo to cure a person of a genetic disease, then in theory, it is possible to create a ‘designer baby’, where hair colour, eye colour and perhaps things like height and intelligence are manipulated, which massively impacts

The possibility of humans being able to edit an unborn baby’s traits has led to strong feelings of both support and opposition. The possibility of gene editing first became a reality over three decades ago. Scientists began using viruses to alter DNA sequences, and with these changes they created transgenic animals. These animals have altered physical, cognitive, and social characteristics then they had previously. For almost all of this time, the technology used was not very precise or efficient. This all changed with the development of a group of gene editing technologies, the most powerful of them being the CRISPR-cas9 system. And in April 2015, it was announced that CRISPR was used to make the first gene edits in human embryos. This was the first time for germline gene

For years, scientists have discussed the notion of editing a human genome to completely banish all inherited diseases by replacing a mutant gene with a healthy one. This idea became popularized in 1996 when Scottish researchers successfully cloned a sheep. DNA from an adult sheep was implanted into an unfertilized egg and then placed in a surrogate mother. This resulted in an identical twin carrying the same DNA as the original adult sheep. This was the first time many people considered cloning as a possibility for the future and this experiment sparked controversy across the world. Science has developed immensely since 1996 and in todays news there is a lot of talk regarding human genome editing. The biggest issue is the ethics of changing a natural code using new technology that has not been studied thoroughly. “The technology is new, and the risks of a mistake are magnified by the fact that the genetic changes would be passed along to offspring” (Adams). While many people are opposed to gene editing, some argue that it could be the biggest breakthrough of modern science.
