CRISPR-Cas9 Synthesis
CRISPR-Cas9 is a method of gene editing that provides researchers with a way of precisely targeting a specific string of DNA. CRISPR is a sequence of repeated DNA located in the genomes of bacteria that are used in immune systems to help protect our bodies from infecting viruses. This method involves the use of an enzyme known as Cas9 and a guide RNA. A virus’s DNA becomes spacers in the CRISPR sequence when the new virus infects the bacterium. This sequence will then begin the process of transcription in which it will become a guide RNA. This RNA will then be used to guide the Cas9 to locate the target sequence within the viral genome, so that the Cas9 can snip off this sequence and kill the virus. Simply put, it’s like using scissors

    The technique gives a high frequency of point mutations that is distributed randomly in the genome (Kurowska et al., 2011). The high throughput strategy uses a chemical mutagen, Ethyl methane sulfonate (EMS), and a technique that identifies single base changes within the target gene. With the TILLING method, multiple alleles are amplified by PCR to for DNA heteroduplexes which are double stranded nucleic acid. When it is heated and cooled, a bubble forms where two DNA strands are mismatched and is cleaved by single stranded nucleases. Mismatches can be because of induced mutation or natural variation (Henikoff, Till, & Comai, 2004). The cleaved products are run on a gel to be separated by…

    Crispin: The Cross of Lead, is about a 13 year old boy named Crispin. Crispin lived in a village called Stromford with his mother. At the beginning of the book Crispin’s Mother Died. Later on, he escapes the village because he was proclaimed a wolf’s head by John Aycliffe. He is in an abandoned village when he meets a man named Bear. Bear takes Crispin as his slave. Later on, Crispin becomes Bear’s apprentice. Bear teaches him how to play a recorder and juggle. They travel from village to village performing. They stay at a place called the Green Man Inn. When Bear sneaks out to a secret meeting, Crispin is left at the Inn alone. He goes out to find Bear because he thinks Bear is in trouble. Bear gets captured by the soldiers and…

    Genetically modified (GM) animals are the result of deliberately changing a genome through genetic engineering. The process of modifying the genetic composition of a mammal scientist starts with Deoxyribonucleic acid (DNA). DNA makes up the genes of all living things and by using DNA sequencing scientist are able to identify a specific gene. Each parent passes along one set of genes, each set forming on side of the two sided DNA strand. The two DNA strands are known as polynucleotides. Similarities found between species prompt scientist to research and theorize utilizing variations found during research.…

    CRISPR stands for “clustered regularly interspaced short palindromic repeats” and is used to “revolutionize the field of genome editing” (Doudna). This is a very controversial subject because there are two sides that people are on and debating about. The first side supports this system because it says that you can genetically change a person’s genes so that if they have a disease or mutation, they can be cured. However, many people are supporting the second side as well. This side or the second side says that you can genetically modify your babies to how you would like them and create the baby you want.…

    In the past few years CRISPR has become a debatable issue consisting of both pros and cons. Under certain circumstances, scientist should be able to edit the human genome. CRISPR has potential to help generate electricity, create cells that are disease-free and possible save the lives of endangered species. In addition, CRISPR may help to extend the shelf life of vegetables or enable humans to live longer (Park 69-70). However, little is understood about the full effect of gene editing and some worry about how easy it is for CRISPR to fall into the wrong hands. Others fear that scientists are moving too fast and without enough precautions (Park 118). Ultimately, CRISPR advantages are being weighed heavily against the disadvantages.…

    CRISPR Ethical Issues

    So, when virus inject their DNA into a cell, and someone doesn’t have an immune system, the virus would usually take over the cell and be inserted into the genome, slowly killing the entire cell. The idea with CRISPR is that proteins are transcribed and translated by the Cas system, in addition to Cas making the spacer DNA transcribe special crispr RNA. The RNA fits into the protein and together they break apart the viral DNA and stop the infection before it has even begun. It is another issue if the genome doesn’t contain the right spacer that matches. In this situation, the cas system create a different type of protein, which takes the DNA, breaks it apart and copies it into the crispr system as a new spacer. All the spacers that are in the genome are unique, because they contain the “history” of previous infections, so it will keep us from being infected by the same virus. Now, this CRISPR system works the same way in everyone who has an immune system, but scientist have discovered a way to use the system to make changes in the genome however they…

    Modifying genes could be a way of preventing unwanted traits or enhance characteristics (Against Designer Babies, Sheldon Krimsky). Unfortunately, CRISPR is a first generation tool, so there is no possibility no damage will be done to the baby. As well as no security, the baby will not have any life-threatening defects, as it is known that “curing” one disease causes another. In fact, this will create a bad relationship between parents and children (The Ethnic of ‘Designer Babies’, Tia Ghose), since the children have no choice in being modified. Using babies to alter their characteristics is using them as science experiments since there are over one hundred genes that account for each trait and fifty genes account for three percent of one gene (Against Designer Babies, Sheldon Krimsky). With many parents willing to allow these experimentations to occur on their baby, it will come at a huge…

    Today people die from old age, diseases, heart failure, and other hereditary problems, if they are lucky enough to live that long. If not, then some children die of sudden infant death syndrome or heart problems or any other neo natal disease or complications. This is a big problem in today’s society that today’s medicine can’t always solve by itself, sometimes it takes a God given miracle for a child to survive. But what a lot of people don’t know is that there is a brand new science that has been discovered and is on the verge of being implemented on humans. Clustered regularly interspaced short palindromic repeats or CRISPR is something that naturally occurs in bacteria but can be manipulated in our favor to “better” the human body. Basically…

    Brave New World Analysis

    The science of today can create super baby's, which Huxley predicted by engineering everyone through conditioning. The debate between nature vs nurture has battled for over a century and half, as to whether genes or environment play a role in human nature. Steven Pinker a Canadian psychologist, says that genes are the reason for human behavior. Pinker reinforces his idea by talking about children, “[Anyone with a] child knows that kids come into the world with certain temperaments and talents” (Pinker, 2003). Environmental factors do not play a detrimental role in the development of children, the genes determine how the child will work. Some genes may cause children to have a bad temper, while other genes may make children behave. To edit genes was thought of as a game changer, to be able to remove unwanted traits such as the cancer gene or make people immune to every known bacteria and virus known to man. Today there is CRISPR or Clustered Regularly Interspaced Short Palindromic Repeat. According to Harvard University “CRISPR changed not only the way basic research is conducted, but also the way we can now think about treating diseases” (CRISPR, para 1). Humans can edit genes in other humans to remove genes that are thought as being unworthy or useless. CRISPR can be similar to Brave New World but because of ethics and regulations on changing and or…
