Genetically modified organisms (GMO’s) have replaced our diet with genetically altered foods, which have adversely affected human health as well as local communities. Genetically modified organisms (GMO’s) are a broad group of plants, animals, and bacteria that are engineered for a wide variety of applications ranging from agricultural production to scientific research. The types of potential hazards posed by GMO’s vary according to the type of organism being modified and its intended…

The article, The Truth About GMOs: The Good, The Bad, and The Really Ugly, proves that “according to the Grocery Manufacturer Association, 75% of conventional processed foods contain GMOs” (Scipioni 1). The research done on these genetically modified foods is not extensive enough to justify the long term effects they have on an individual’s health. The majority of foods that common Americans eat everyday are genetically altered. The reason why consumers buy these unsafe foods is because they…

Introduction Background This experiment pertained to identifying an unknown bacterium. This bacterium was retrieved from a member of our group’s hand. Bacteria are prokaryotic, but like all other living organism there are many genus and species. Through experimentation these unknowns can be found can be brought to light. Bacteria can be classified either gram-positive or gram-negative. These groups differ by the composition of their cell walls. In particular, the difference in the composition…

The Bioethics of Bioterrorism I. Ethical Question It is universally accepted that bioterrorism, or the use of viruses and bacteria to spread disease and cause panic (“Bioterrorism”), is wrong and inhumane. However there is still a question as to whether or not research into biodefense, or the mechanisms used to battle bioterrorism (“Biodefense”), should be allowed. II. Background As previously stated, bioterrorism is the use of viral and bacterial diseases to infect populations and incite…

QUESTIONS for The Hot Zone by Richard Preston PART ONE: “THE SHADOW OF MOUNT ELGON” 1. Charles monet was a loner who lived by himself in a little wooden cabin on the private lands of Nzoia sugar factory. He was fifty-six years old and his job was to take care of the sugar factory’s water pumping machinery. 2.Mount Elgon is a volcano located on the border Uganda and Kenya, Mount Elgon is an extinct shield volcano. 3.Monet gave the virus many opportunities to accumulate a new host, For…

Genetic modification is a widely debated subject since there is so much known about it yet so much that is still unknown. Some people don’t even know what genetically modified food is and how it came about. It was best said by John Donovan when he said “…nature has many unknowns, but one certainty is that tomatoes and fish do not have sex with each other” (Donovan). The experiment he is referring to is one of the most infamous early attempts at genetic modification. After Donovan said this quote…

still performed as if all seven of the Gram positive options were still possible. Secondly, the amounts of tests performed on the Gram positive unknown led to Listeria Monocytogenes as the only possible candidate. A non spore forming test removed all Bacillus and Clostridium species as a possibility. A positive catalase test removed Lactobacillus species as a possibility. A negative nitrate test removed mycobacterium species as a possibility. And, a positive phenol red arabinose test removed…

(36), plant protoplast formation and treatment of eluent discharged from fruit processing units (Tanabe et al.1987) (37). Although the main sources of acidic pectinases are fungi, alkaline pectinases are produced from alkalophilic bacteria, mainly Bacillus…

I had been pondering this question for a while “how will my parents react when I tell them that I have decided to join the LDS church? The worst part of it all is that I didn’t ask permission to start speaking with the missionaries in the first place.” I was literally weighed down by fear as I crossed the threshold of my parent’s front door that evening. “I made this decision and I am willing to deal with the consequences,” I thought to myself. Somehow the brightly colored walls of the living…

are unable to establish persistent infection in animal models. Consists of 2-6 unipolar flagella.Dysfunction of flagellar biogenesis have a strong impact on motility and infection. Vibrio cholerae: gram negative aerobic or facultative anaerobic bacillus. Hallmark of the disease , cholera, is profuse secretary diarrhea. Biofilms are likely a form in which clinically relevant V.cholerae is taken up by humans, providing a concentrated infective dose. It has single polar flagellum(monotrichous)…
