Position Paper The stigma against genetically modified foods kill people. How, you think? How does simply an idea cause the death of thousands of people? First of all, genetic modification is the direct manipulation of an organism 's genome by changing the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. Genetically modified organisms are food crops that have been created through the application of transgenic,…

While genetically modified organisms have been around since the 90 's, they are still a highly debated topic all the way into 2016. The use of many GMOs create a hot bed of debate, but the pros of GMOs far outweigh the cons. The struggle for the population control and world hunger are evident and also uncontrollable, as we approach 9 billion people it is eminent that we will run out of needed resources such as food, gas, and space. What if I told you that the issue of food could be easily solved…

rate. This large surface area in their lungs comes from many small alveolar sacs. Since lungs act a little like balloons they prevent the whales from diving to a certain depth within the water. The lungs in a whale are small in comparison to its body mass. There is nitrogen present in the body tissues of a whale and they need to remain dissolved so that it does not become converted back into a gas and affect the whale physically. So the whale has adapted to have a flexible ribcage so it can…

referenced to the ladder to determine the molecular weight of the MBP-AP and WT-AP proteins. Then the UV absorbance of the two proteins from 240 nm to 340 nm is determined using a nanovolume cuvette. The absorbance at 280 nm was then used in conjunction with data from previous experiments to determine the concentration of the MBP-AP and WT-AP protein samples. Results of experiments showed that the SDS-PAGE gel yielded expect bands and the approximate molecular weight of wild type alkaline…

Control Genetic Engineering Genetic engineering is the deliberate modification of the characteristics of an organism by manipulating its genetic material. Genetic engineering can: cure inherited diseases, modify plants so that they may fight pollution and make bigger/faster growing fruits and vegetables, make cats to glow in the dark, and cows that pass less gas. There are both pros and cons to genetic engineering. With that being said, society wants to know should it be controlled by law. In…

DNA ISOLATION INTRODUCTION: Deoxyribonucleic acid (DNA) isolation is an extraction process of DNA from various sources. Methods used to isolate DNA are dependent on the source, age, and size of the sample. Despite the wide variety of methods used, there are some similarities among them. In general, they aim to separate DNA present in the nucleus of the cell from other cellular components. Isolation of DNA is needed for genetic analysis, which is used for scientific, medical, or forensic purposes…

goal of the PCR is to produce required amount of the target DNA region that is be analyzed. PCR amplified DNA is sent for sequencing and visualized by gel electrophoresis. It also can be cloned into plasmids. PCR is used in many fields of medicine, molecular biology research, medical diagnostics, and ecology. It is fast and inexpensive technique used to amplify DNA and RNA fragments by 107 times. The polymerase chain reaction was…

in Figure 1a. The banding modality of ISSR-PCR fragments using five qualitative primers to fingerprint the Cajanus cajan L. cultivar was documented in Table 2. The results of ISSR fingerprint exhibited 14 amplified fragments. The highest band mass was made with primer HB9, and the lowest band size was produced by primer B89. The size of the amplified fragments was ranged between 830 bp and 240 bp in length. The ISSR banding pattern obtained with the five primers was shown in Figure 1b. 3.2.…

Discuss the similarities and differences in DNA replication between eukaryotes and prokaryotes. Are the changes in eukaryotes adaptations? Explain. Introduction Before we start our discussion, let us refresh our memories; cells are the absolute smallest building blocks of life, each manifesting a sophisticated design. Broadly speaking, the cells are divided in eukaryotes that contain membrane-bound organelles; and prokaryotes that do not (Diffen, 2007)—in short, prokaryotes are both simpler and…

1. ABSTRACT: A total of 552 serum samples of sheep, goats and cattle from different localities at Assiut governorate, Egypt were screened for qualitative analysis of the BTV antibodies using a commercial competitive ELISA (cELISA) kit. The results showed an overall percentage of BTV positive sheep, goats and cattle serum samples were 41.86%, 24% and 85.42% respectively. A highest percentage of seropositivity was found in Arab El- Awamer farm(100%), followed by Abnoub( 63. 64%), Sedfa(11.…
