Introduction The purpose of this lab was to test a plant based food sample for the presence of genetic modification. Genetic modification (GM) is the process of altering the DNA in an organism’s genome by “inserting a gene or genes from a donor organism carrying a desired trait into an organism that does not have … Read more
Introduction 14.7-23.5 million people with autoimmune diseases in the US and is among the top ten leading causes of death (Khan, 2015). Immune responses and systems of human and rodent males and females differ in significant ways after puberty. Men and women can get the same types of age-related autoimmune disease, yet males experience them … Read more
A Genetically Modified Organism: Benefits and Risks A genetically modified organism is an organism that has been genetically altered to present certain desirable traits. The general topic of the overall health and safety of genetically modified organisms is a widely controversial topic. Many people believe that genetic engineering has a negative effect on every aspect … Read more
Introduction Energy can be found anywhere in the world, and it stays that way, “it cannot be created or destroyed” from the law of conservation of energy. However, every energy can be converted, for example, a kinetic energy can be converted to an electrical energy and when a dynamite explodes it is the chemical energy … Read more
Abstract We describe the isolation and characteristics of a novel thermophilic bacterium from soil. The organism is a member of the Anoxybacillus genus based on phylogenetic analysis of the 16S rRNA gene. The 16S rRNA of the organism shares >99% sequence identity with those of two species, A. rupiensis and A. geothermalis. We named this … Read more
The American Museum of Natural History has a recent exhibit called, “Meet Your Microbe.” In this exhibit, attendees at the Natural History Museum learn about the microbes contained within the human body. These microbes are not only plentiful but they are also a vital part of the human ecosystem. Not only does this exhibit teach … Read more
Introduction Frisbees, for many years now, have been a source of recreation used commonly by people belonging to all age groups. Frisbees or flying disks are the base for many games such as fricket, disk golf, etc. The disks made of plastic can travel long distances. The history of the flying disk goes back to … Read more
Abstract The major objective of this experiment was to observe if the integration of pGLO, as a plasmid vector, into the genome of Escherichia Coli, would result in bacteria that glows. It was based off of three environmental factors; LB nutrient broth, the antibiotic ampicillin, and arabinose sugar. The transformation vector used included the use … Read more
SEQUENCING Computer scientists are engaged in the analysis of large datasets generated through Next Generation Sequencing approaches. Much of this type of research will require extensive collaboration with biologists. This course was designed to prepare students for NGS based collaborative research by teaching the vocabulary and a basic understanding of the tools used in molecular … Read more
This study was conducted to evaluate the physiological indices in relation to the screening of cold tolerant rapeseed (Brassica napus L.) genotypes for drought tolerance and study yield and yield components under early and late season water deficit stress. Six rapeseed (Brassica napus L.) genotypes including Karaj 1, Karaj 3, Opera, Okapi, Licord and Modena … Read more
The preservation of bodies has been around for thousands of years. When one thinks back to where everything all started they would most likely think about the Egyptians and the rituals they used back then. As the years go by, human preservation has changed drastically. In this day in age, there are many different methods … Read more
Physiological studies of plants reveal that diffusion of ethylene, into and out of plant tissue, is responsible for regulating and stimulating various growth and developmental activities such as ripening of fruits (Yang, 1995; Alexander and Grierson, 2002; Atta-Aly and Brecht, 2000; Klee, 2002; Fan et al., 1999; Fan and Mattheis, 2000), opening of flowers, and … Read more
ABSTRACT: Hyaluronic acid is a naturallyoccurring polysaccharide possessing unique properties, such as high viscosity and water retention, tunable molecular weight, and lack of immunogenicity and toxicity, that allow for its usage in biomedical, pharmaceutical, food, and cosmetic industries. Two primary production methods exist for hyaluronic acid: extraction from animal tissues and biological fermentation. Each production … Read more
Atomic structure: The atomic structure of all things involved in this process is very important. It allows us to understand how all things are connected and can bond together to complete the process. An atom consists of a nucleus which is located in the middle of the atom, this includes positive and neutral particles called … Read more
Stress is said to be the relationship between a response and the environmental conditions that caused it. Stress initiates a reaction due to conditions that puts one under a significant amount of pressure, possible threats, or the individual working under high demands (Dobson and Smith 2000). For an animal, stress may be seen as the … Read more
