Over the span of 35 years, our society has developed research towards Genetically Modified Organisms (GMOs).These organisms have provided many benefits to the society through nutritional value and over the years of being developed, there have been negative theories that have arisen in the eyes of skeptics. Although there are many legitimate concerns toward GMOs, labeling and regulating Genetically Modified Organisms can alert customers of the dangers and decrease negativity by informing them of…

Genetic engineering is an alluring and powerful branch of science and technology. The Merriam-Webster dictionary defines genetic engineering as, “the group of applied techniques of genetics and biotechnology used to cut up and join together genetic material...from one or more species of organism and to introduce the result into an organism in order to change one or more of its characteristics”. Genetic engineering has led to some of the most remarkable advancements in agriculture and medicine.…

Discussion When comparing the banding patterns of the crime scene to those of the suspects, the resulting gel indicates that Suspect 2 was at the scene of the crime. Although enzyme 1 produced identical DNA fragments across the gel, enzyme 2 did not. This is evident in lane D and possibly indicates that this enzyme was unable to bind to recognition sites similar to the crime scene DNA in well B. Thus, it produced a DNA fragment smaller in size that travelled further. Since the DNA evidence in…

The result from the transformation process showed no colony growth on the agar plate, which means no plasmid DNA got inserted into the vector (Table 1). Thus, the transformation was considered unsuccessful. With that being said, the gene was not transferred among the bacterial cells. The reason could have been that the agar plate had a strong concentration of antimicrobial drug, so the bacteria may have been unable to grow under such condition. Another reason could be that the cell did not get…

Genetic mutations are the source of numerous hereditary diseases. This has been discovered by the comparison of two DNA sequences with bioformatic software. Two sequences are aligned and compared in order to locate mutations in the DNA (Module 4 Protocol,1). Escherichia coli aka E. coli was used as the test subject in this lab because it employs lac operons while transcribing mRNA. An operon is a unit of linked genes that regulates genes in charge of protein synthesis. A lac operon requires…

The Truth About GMOs: Persuasive Essay The discussion of genetically modified organisms (or GMOs) can cause quite a heated debate. GMOs are created by a process called genetic engineering, also known as genetic modification. During this laboratory process, the DNA of one species is removed and then added to the genetic makeup of another species (Smith, GMO Education). GMOs can supposedly increase yield, produce herbicide/insecticide tolerant crops, and in some instances they have benefited…

Cloning Background information: Cloning is a process where the DNA is replicated. It is done by having the DNA of an organism, human or animal, is put into an egg whose DNA is removed and when the egg is stimulated, the egg starts to duplicate. The results would be DNA is which genetically similar to the original organism. Cloning can also be applied to cells. The first mammal that was cloned successfully from an adult cell was the sheep named Dolly in the year 1996 by Scottish scientists in the…

3.1 The isolation of Aeromonas hydrophila When using selective medium developed by Rimler and Shoots (1973), we obtained 95 bright yellow colour isolates with white edge which lead to the alleged as A. hydrophila. Of 95 isolates were further screened using SNI 7303 (2009) methods which produce 56 isolates. The isolates were further screened using Dorsch et al. (1994) and Cascón et al. (1996) method. 3.2 Bacterial DNA isolation and Identification. DNA amplification using Dorsch method…

Globalization, even with all its health disadvantages, should not come under fire so readily. The movement of goods, food and people have become an integral part of what we enjoy as a society that most of us take for granted, exotic fruits and vegetables available in our supermarkets almost every day of the year, competitively priced goods imported from other countries mean we have money left over for our hobbies and that vacation you take every year to visit other countries are all made…

Genetically Modified Organism Everyday Usage What is your stance on genetically engineering organisms to contain better genes within agriculture? Over the past decades gene engineering has been a huge topic of discussion between the public. Questions have erupted on whether the benefits from GMOs (genetically modified organism) outway the problems and on whether it is morally right to modify creatures for humans satisfaction. With a little education one will find that gene manipulation should…
