Ehrlich searched for a/an ________. This is a chemical that would hunt down and destroy a pathogen without harming the infected host.…
In this lab, the goal was to transform the bacteria e-coli to glow in the dark (or under a black light). Four plates were set up with agar in them for the bacteria to feed on and grow. Changes were then made to the bacteria. One plate was the control plate, having only the LB or agar for the bacteria and negative pGLO, which is the liquid not containing the plasmid. This is the plate that was compared with the three others in order to identify the changes. The second plate contained negative pGLO, LB, and ampicillin. This is to see whether or not the bacteria will become resistant to the ampicillin and grow, or not be resistant and have no growth. The third…
A few pros would have to be, Foods can be modified to have more essential vitamins and nutrients, or simply taste better. By doing this, the increase in variety, and convenience for foods allows others to get their needed vitamins, and nutrients from just plants rather than having to buy supplements. Genetically modified foods are part of our daily diet and reassuringly enough appear to be quite healthy for us. Some would see this as a plus because everyone is looking for new ways to be healthier and GMO's give you that option. There are no known health risks so it is a matter of belief whether or not you want to trust in genetically modified foods. If you are willing to try GMO's then you will be surprised to see that the downsides are very…
Genome constitutes the complete genetic make-up of an organism; its complete DNA or RNA. It contains all of the information needed to build and maintain that organism. The field of Genetic engineering is primarily concerned with manually tweaking the genome of the target organism, in order to engineer mutations with newer genetic traits with the aim of introducing specific desirable traits into a specie. Transgenic biotechnology opens a new world of possibilities, gives us hope for a better, stronger and healthier world but not everyone has such a positive outlook on genetic…
In this experiment that we performed, there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating, identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining.…
Genetically modified foods are beneficial for our society because of the nutrients that may be added to foods and the greater ability to produce these foods. While some people argue that genetic modification is still a new technology that should be researched further, others will agree that the benefits definitely outweigh the drawbacks. Society today has all kinds of new technology at its fingertips and should be allowed to use this technology to enhance certain things to better the world.…
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.…
Genetic engineering (GE) is also known, as genetic modification is the process of organisms that are genetically modified. In this process the goal is to transfer new DNA to an organism so it can improve its habits and make new cells.…
Genetically modified organisms (or GMO’s for short) have coasted their way into every single part and place of America’s current food sources. GMO’s are genetically modified or created organisms to, according to some scientists, end world hunger. They are very easy to grow in certain environments and fuel big business while proving the abilities to feed the masses with an extremely low cost. But what are the long term costs? GMO’s are proven to be very detrimental to health, damaging to organics, ruining the seed trade, all while being currently protected by federal law. GMO’s are not a legitimate and safe food source and should be made illegal.…
However, CRISPR/Cas9 system can invite an unhappy future if people misuse the technology. For example, designer baby. Of course, there are pros of designer baby, like “reducing risk of genetic diseases, getter chance the child will succeed in life, increased life span” (Hanson). It also can be that people are enable of organ transplant, and give birth to children of same-sex couple. On the other hand, there are cons, for instance, end of embryos, making a gap in society, loss of individuality” (Hanson). “making a gap in society” means only rich people can use the technology and control the world. What is most problematic is parents can edit children’s genome as they like. Even if their children, they are not their possession. Parents do not…
GMO stands for Genetically Modified Organisms. This means they undergo a certain forced process where they are introduced to bacteria and viruses to receive different traits to resist diseases or the tolerance of pesticides. GMO crops have been in the news for a very long time and it's safe to say there are some pretty heated arguments about the topic. These foods that have been introduced to GMO have been tested with the World Health Organization and humans are safe to consume them. All living things contain DNA of the same four blocks, these blocks are are known as nucleotides. The new gene inserted only restrains the modified organism to deliver the desired trait.…
The most prominent and perhaps the most acceptable reason given for genetic engineering is its potential use in preventative medicine. A few cells from an embryo could be genetically analyzed to detect harmful mutation or predisposition towards disorder, at which point action could be taken either through somatic cell or germ-line gene modification. In 1993, the gene that causes Huntington's Disease was located, and scientists are currently trying to determine its normal function (The Benefits of Genetic Engineering). Assuming researchers succeed in this endeavor, genetic engineering could then be used to eliminate a debilitating and ultimately fatal disease that affects approximately 30000 Americans and that has the potential to affect 150000 more through genetic inheritance (Huntington's Disease). In 1997, a group of scientists successfully diagnosed familial adenomatous polyposis coli, the dominant cancer predisposition syndrome, in three preimplantation embryos. This type of cancer predisposition affects 1 in every 10000 people America, Britain, and Japan, making it a relatively common malady (Ao, 140). Schizophrenia has been shown to run in families; even adopted children of schizophrenic parents are ten times more likely to develop schizophrenia, regardless of whether or not their adoptive parents are affected (Bernstein, 518). Lastly, birth defects such as downs syndrome could be eliminated through genetic engineering (Resta).…
Genetic engineering could very well be the next age of technology.with diseases and disorders on the rise many are looking toward stem cells and different organs to heal and transplant to people. with this comes boundaries that many think should not be crossed. This is very much like an instance in a story, Frankenstein where a man of boredom was trying to create a creature that can think and feel. Frankenstein was born a robotic human like creature, what if we could do that in the real world would people approve? In the passage of Bill Nye, he talked about cloning and how alot of people believe is not ethical and goes against the laws of nature and what some believe to be satanic, going against the creation that many think is the work of god.…
“Should we manipulate the DNA of bacteria?” This is a question that has no definite answer, but a limitless amount of controversy. Since DNA is the code within each and every cell that instructs them on how to function and bacteria are rapidly reproducing microbes, genetic engineering is something to be considered. In fact, Bacteria were the first organisms to be genetically engineered. Modifying or manipulating the DNA of microbes and bacteria should continue to be allowed because it can be used for human benefit in regards to pharmaceuticals and as a fuel supply.…
