Pros And Cons Of Genetic Modification

Improved Essays
Gene modification is the process of altering the DNA of a living organism such as humans. CRISPR-cas 9 is a genome editing tool where scientist and doctors remove, add, or alter sections of the DNA sequence. It has the capability to treat chronic diseases, create designer babies, and improve the quality of life. Therefore, doctors should be allowed to perform gene modifications on humans.
According to Centers for Disease Control and Prevention, in 2012 “one hundred and seventeen million people in America had one or more chronic health conditions.” Chronic health conditions such as cancer, diabetes, and myopia are deadly diseases that are heritable conditions. Meaning that these diseases are capable of being passed down from one generation to

However, with the establishment of CRISPR system heritable diseases can stop spreading. This new invention disrupts a specific gene by editing the DNA of a human. Therefore, it can help to minimize the number of people who are affected by chronic health conditions and die yearly due to chronic diseases. In a recent study, two children with an “inherited disorder of the immune system”; a disease that lacks immune cells to fight bacteria, viruses and fungi, underwent gene editing. Several days after the procedure, doctors began seeing results in their patients. The patients were no longer having diarrhea and skin rashes, which are the symptoms of the disease. After a days in the hospital the patients were able to go home and enjoy “normal growth and psychomotor development.”.(U.S National Library of Science 1). The transfer and modification of the gene was …show more content…
Scientist in China have already begun experimenting with embryos of humans and dogs. Using the CRISPR system, scientist deleted a gene from a beagle’s embryo called myostatin. Myostatin blocks muscle production and by cutting the gene the beagle’s body could produce extra muscle.(The Telegraph) After the experiment was performed, the female dog showed physical difference. For instance, the beagle “displayed obvious muscular phenotype” in her thigh muscles that were very large compared to a normal beagle. The gene modification of myostatin successfully worked with no repercussions. Scientist in China had decided to experiment on dogs to see how what the effects could be on humans. According to Liangxue Lai, a researcher with the Key Laboratory of Regenerative Biology at the Guangzhou Institutes of Biomedicine and Health, “dogs are very close to humans in terms of metabolic, physiological, and anatomical characteristics.” Therefore, due to the beagle experiment, if gene modifications were allowed on humans, positive results would appear. Hence parents would have the opportunity to pick certain traits for their babies. For instance, if poor eyesight runs in the genes of both parents, perhaps they would like their baby to have excellent eyesight. If gene modification were to be performed on the embryo, then the parents would be able to eliminate the headache of frequently seeing an optometrist and/or purchasing new

    The system allows researchers to easily create many animal models of diseases that were previously found to be difficult to do because creating these models was slow and costly. The system could be used to correct mutant genes that cause genetic disorders, getting rid of the disease overall. In 2014, a study was done by scientists at MIT in which the CRISPR/Cas9 system was used to cure mice of a rare genetic liver disorder. There are a wide variety of other genetic disorders that have the possibility of being treated with this biotechnology. These include hemophilia, huntington’s disease, cystic fibrosis, and muscular dystrophy.…

    In 1987 scientists have found what is now called CRISPR-Cas9 (Clustered Regularly Interspaced Palindromic Repeat), which is a tool for biologists to make eugenics viable. Moreover, it’s a powerful, precise, and a surprisingly cheap tool that geneticists use to “cut” open and edit pieces of the genome of the DNA sequence. This powerful tool, CRISPR, uses blades on the DNA strand to cut/break it in half at a targeted location to match the (single interfering RNA) siRNA sequence. The siRNA is a pre-designed sequence located within an RNA scaffold that binds to the DNA and the sequence to guide Cas9 to the proper section of the genome that ensures the enzyme makes a precise cut across both strands of the DNA. For example, bacteriophages hunt bacteria in the ocean killing 40% daily.…

    CRISPR Cas9 CRISPR Cas9 is a gene editing tool that can be used to edit, delete, and change parts of the genome. What makes CRISPR Cas9 different from other gene editing techniques such as Zinc Finger Nuclease (ZFN) or Transcription Activator-Like Effector Nucleases (TALEN) is its targeting efficiency ability. For example, ZFNs and TALENs could only reach targeting efficiencies from 1% to 50% in human cells. On the other hand, CRISPR Cas9 had a much higher rate at greater than 70% in Zebrafish and plants. (Reis, 2014).…

    For scientists who are waiting for an alternative to existing genome editing tools, Crispr-cas9 is the solution which is comparatively easy and effective in using. Crisper allows the researcher to edit, target, excise and stitch genes of their choice between two end cuts. Crispr has the potential to make such advances which researchers used to dream about. It worked so well, scientists began to issue ethical statements for its use particularly about the power of Crispr to change germline in humans which presents a hotly debatable issue. Genome editing in human germline could have unpredictable effects on future generations.…

    CRISPR is a technique that made genomic editing significantly easier. CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated protein) is a RNA-guided nuclease for precise genome editing in diverse organisms. In 1987, when scientists were studying the bacteria's immune system, they discovered a pattern of short, repeating, palindromic DNA sequences separated by short, non-repeating, "spacer" DNA sequences (Figure 1). How CRISPR/Cas works in bacteria: As shown in Figure 2, the CRISPR immune system protects bacteria from repeated viral attack by three basic steps: Step 1) Adaptation – When bacteria are invaded by a foreign DNA from a virus, they can duplicate and then incorporate the segments of the foreign DNA into their genome as "spacers" between the short DNA repeats in CRISPR.…

    Recently, the scientific world had witnessed a revolution in genetics - CRISPR. Also known as the “clustered regularly interspaced short palindromic repeats,” CRISPR (pronounced “crisper”) in used in the process of splicing parts of the human genome in order to check and correct genetic errors and defects. As stated by Jennifer Doudna, a chemistry and molecular and cell biology professor at the University of California, Berkeley, “It is enabling the sorts of genetic modifications that in the past have really been a dream.” Researchers have concluded that CRISPR may be beneficial in fixing the genetic mistakes that cause diseases such as Huntington’s and sickle-cell anemia. Yet, what’s better is the fact that CRISPR has the potential to permanently fix these errors in the gene.…

    Altering the genes of a human adult is a procedure that is already taking place in America today. However, altering the genes of embryos is similar to altering adult genes, but involve different steps of eliminating unwanted genes. The main aspect of altering embryos is that there has to be a large amount of them to work with. For example, in order to properly alter the genes of an embryo, scientist created 58 embryos from the sperm of a male with the mutation and combined them a female donor without the mutation’s egg. Then they used the CRISPR system to remove the mutation out of the gene.…

    The increase of knowledge regarding the topic altering genes has become rapid and have open and paved the hope of designing your own perfect baby. Even today, the use of reforming and adjusting the genes of an unborn child is being put in effect. “Techniques of genetic screening are already being used, whereby embryos can be selected by sex and checked for certain disease-bearing genes. This can lead to either the termination of a pregnancy, or if analyzed at a pre-implantation stage when using In Vitro Fertilization (IVF), can enable the pregnancy to be created using only non-disease bearing genes” (Steere, 2011, para. 6). Altering the babies genes can not only harm the baby, however, can also terminate the baby.…

    The concept of genetically engineering humans was once confined to the franchises of fiction – stories of half-humans and shapeshifters, transgenesis and cyborging, genetic superpowers and mutations. The list goes on, but one crucial thing has changed – now these once impossible ideas have seemingly become attainable. Ever since female scientists in the United States and Sweden discovered CRISPR-Cas9, the scientific community has been debating over how to use this new power in their hands. Germline gene therapy is a form of genetic engineering that involves transferring DNA into reproductive cells to treat disease, so that the inserted gene will be passed onto future generations. There is currently much controversy over this topic and whether…

    Gene editing is the alteration of genes in germ cells which become either sperm or eggs and are inheritable to future generations. Genetic editing has been used in agriculture to enhance crops, it is now being explored in humans too. This technology could potentially eradicate genetic diseases and prevent future generations from passing it on. Gene editing is done through the CRISPR-Cas9 system, where the embryo is edited to the desired outcome. It identifies and attacks the viral DNA and then it changes the targeted DNA strand that can be replaced or turned off.…

    Some believe that giving parents the option of genetically engineering their baby will result in eugenics driven by egoism. People might take advantage of germline manipulation by creating embryos that will be their own idea of what is perfect, thus objectifying and commodifying children. Some opposers even say that because these embryos will not have a say in whether they want to be modified or not, their rights will be taken away. Furthermore, regulating laws ensuring that genetic modification is used only for the correction of genuinely medical genetic conditions as opposed to enhancing a child’s appearance will be nearly impossible. Rich parents will use…

    One of the biggest problem of using CRISPR is that it can introduce off-target effects or change bits of the genome far from where scientists had intended. Any human embryo alter with CRISPR today would carry the risk that its genome had been changed in unexpected ways. Consequently, this technique will require a large number of stem cell in order to obtain the desirable genetic changes and carefully study and check for mistakes before producing an egg. For this reason, it is this experiments should be done in animals first and once all the problems associated with this technique are solve, maybe they can think about safely and responsible perform them in human cells…
