Viruses are capsules with genetic material inside. They are very tiny, much smaller than bacteria. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS,
These viruses include the following: herpes, measles, fowl pox, mumps, and equine encephalitis. It was said that Henrietta’s cells helped launch the field of virology. The book also mentions how viruses reproduce by injecting some of their genetic material into a living cell, essentially reprogramming the living cell so it reproduces the virus instead of itself which is a concept we have learned this semester (Skloot, Location
A virus is an infective agent that usually consists of a protein coat with a nucleic acid molecule. Viruses do not reproduce through asexual reproduction. Instead, they attach themselves to the cells in their victim’s body to create more viruses. Over the years, vaccines for certain viruses have been created to help humans combat them. However, for viruses such as Ebola, there have been no drugs approved to cure them.
However, this determination is not always straightforward. Viruses have some, but not all, of the qualities of living organisms, and scientists have long argued whether or not they should be considered as living organisms. In this exercise you will determine whether specimens are non-living, living, or dead. CHARACTERISTICS OF LIFE - STATION LAB Lab Procedures: First, observe the specimens located at each station without touching it.
The capsid carries DNA or RNA1 which give the virus its unique features. In this state the virus is metabolically inert, or it doesn’t use any of its resources to make energy. 1 - Ribonucleic acid: it performs as a messenger for the DNA cells; it manufactures the proteins for living cells using the DNA’s genetic information. When were viruses discovered and who discovered them?
1. A viruses is a non-living infection agent and can be found anywhere. it has no cell organelles. They are eliminated by the immune system. Viruses are the smallest in size of all the microbes.
In the beginning of The Hot Zone By Richard Preston, readers are introduced to the appearance of a virus similar to Ebola that strikes in western Kenya during 1980 and eventually costs the life of Charles Monet, a Frenchman living by himself. When Monet and his friend travel to the Kitum Cave, he returns to his home and becomes ill on the seventh day. The author then describes Monet’s symptoms and illness in graphic details, providing a sense of terror for the readers. When a doctor named Shem Musoke treats Monet in the Nairobi Hospital, he develops the symptoms of the virus himself. Due to the fact Musoke feels particularly unwell after treating Monet, he is then opened up during an exploratory surgery and his liver appears to be red and
Dictionary.com defines a filo virus as “any of several filamentous single stranded RNA viruses.” The Hot Zone is a terrifying true story, by Richard Preston, about the historical stories of Ebola and other viruses such as Marburg and Simian Fever. Richard Preston teaches the reader that nature is unpredictable and that you should always be ready for something new. Dan Dalgard, Gene Johnson, and Nancy Jaax; these are just some of the extraordinary people who have made new breakthroughs in the medical field. Gene Johnson was one of the first discoverers of Ebola and has become an expert on the filo virus.
Boston Smallpox Epidemic of 1721: When smallpox broke out in Boston, Cotton Mather introduced an untested medical procedure called “inoculation”, which would introduce a small amount of the virus to a patient, in hoping they would become immune to it. Many were opposed to it, even though it worked. Many people died due to the epidemic. 31. Common Sense: Thomas Paine wrote a book called "Common Sense", it sold more than 150,000 copies when the population was only 3 million.
To identify if the disease is a virus, there must be evidence shown that the cells do not undergo binary fission; they create new particles like an assembly line. Another trait of a virus is they have a one, single nucleic acid, whether that be DNA or
Long ago, in an unknown village in Greece, there lived 2 brothers. Avarus, a poor and unskilled hermit of a leper. And Bonum, a hardworking merchant who provides shelter and food for Avarus in return for his loyalty and respect. One night, Bonum was invited to attend the Olympics held at their village. Avarus, on the other hand, was not invited to come.
The host of the virus was a monkey. 3. Why didn't the host of the virus die? The host virus didn’t die because the host was immune to the virus.
The particular weapon or better yet biological microorganism that I have chosen to outline this week is that of a particularly nasty strain of disease which has wiped out an unknown multitude of people throughout history. This infectious disease, known as the genus Orthopoxvirus, from the the family Poxviridae and subfamily of chordopoxvirinae, is potentially believed to have laid to waste whole civilizations of people. It also goes by the name “Red Plague”, or in more common parlance, “The Smallpox Virus.” Historically, this virus made its way to Europe sometime between the 5th and 7th centuries. According to Reidel (2005), “It was frequently epidemic during the Middle Ages.

The immune system also can recognize all the millions of the foreign invaders by attacking them and prevent them from enter the body, thus
