[DNA or RNA], that could move from one cell to another" within an organism (Campbell, Mitchell, and Reece 330). This theory asserts that a portion of DNA or RNA initially became separated from the remainder of the cell's genome, and the newly formed virus then migrated into another cell. Isolated fragments of DNA or RNA would be biologically inert; therefore, viruses have been "engineered by the forces of evolution" to maximize their survival as mobile, parasitic organisms (Preston 159). Viruses,

protein coat has a number of T-shaped glycoproteins protruding from it, composed of GP (glycoprotein)2 which is the base and GP1 which is the T-bar. (Southern, 1996) This structure is what inserts itself into the receptors on the host cell. When the virus first gains entry into

system, which then cannot fight off bacteria, parasites, or cancer cells that are attacking the body. It takes anywhere from three to ten years for a person infected with the HIV virus to develop AIDS. A blood test is the best way to know if one is HIV positive (infected with the HIV virus). Symptoms of the HIV virus show up in the first few months; these include fever, chills, nausea, diarrhea, fatigue, swollen glands, and rashes. Symptoms of AIDS are cancer spots on the skin, extreme weight

     Mononucleosis is a viral disease that affects those usually between the age of ten and thirty-five, although a person at any age can get the disease. This disease found in mainly adolescents and adults seems to only occur in those who escaped the Epstein-Barr virus infection in childhood. It is also known as Glandular Fever, because it affects the lymph nodes in the neck, arm pits and groin. It can last anywhere from one to two weeks to six to eight weeks, some people suffer from mononucleosis for months at a

in turn encloses a viral genome. 4. Define host range. It is the limited range of host cells that each type of virus can infect and parasite. 5. List the full steps of the simplified viral reproductive cycle. 1.) Virus enters cell and is uncoated, releasing viral DNA and capsid proteins 2.) Host enzymes replicate the

The purpose of the study by Barr et al. is to investigate an assumed symbiotic relationship between a bacteriophage and the mucus layer of a metazoan host, which may create a defense against microbes to protect the mucus layers from bacterial infection. The mucus layer has about four times more phage than bacteria, which is seen in preliminary testing, and because phage encode hypervariable proteins that may aid in adsorption to bacteria prey, the phages may work to protect the mucus layer be adhering

Medical treatment Medication can be different classes such as anti-fungal, antivirals, antibiotic and analgesics. • Anti-fungal are the medicines that is used to treat the contagious fungal which can mostly be found on the skin, hair and nails. There are different anti-fungal medicines such as ringworm, athlete’s foot, fungal nail infection, vaginal thrush. Ringworm is basically a red rush that can be caused on your body or scalp. Athlete’s foot it’s when the feet’s skin become red, itchy and also

hot-potato. The cause of this contention and angst is a microscopic composition of proteins and enzymes. Though it may not seem like a controversial subject, highly intelligent minds are on both sides of the debate. They argue over the question “Is a virus a living or non-living?” Scientists have arranged parameters that all life must fall in, to be classified as life. This classification system has worked with all forms of life that we have found with

101, MWF 10am Ebola Paper Ebola Virus Over the past couple years, discussion regarding the Ebola virus has gone viral and ignited chaos both domestically and abroad. Ebola is a virus that was discovered back in 1976, but has not failed to grab people’s attention in the recent years (1). It is a very fatal virus that targets the liver and blood vessel lining (10). When Ebola goes untreated it can lead to fatalities or worse off, deaths. There are 5 virus species of Ebola that are linked with

LYTIC INFECTION Once the viral dsDNA has entered the nucleus, if it circularizes itself and becomes an episome within the nucleus, then the virus has entered a lytic life cycle. EBV replication takes place in specialized sites within the host nucleus, referred to as replication compartments8. It is believed that EBV replicates following the rolling circle replication model1. Figure 3 demonstrates how RCR works: after being cut with an endonuclease one strand is replicated continuously and the other
