They will first identify the viral protein that the vaccine will target and then finds the genetic sequence that codes for it‚ that DNA is inserted into a bacterium. The plants are then dipped into a solution of the bacteria where it will soak up the virus. The vaccine will go through many tests and trials to be approved. It has gotten funding from many medical companies and such including DARPA (Defense Advanced Research Projects Agency). It is also approved by the IDRI (Infectious Disease Research

could be repaired through selective mutations. Also genes can be switched on and off to a certain degree. How does gene therapy work? A carrier gene‚ called a Vector brings the normal gene into the target cell. Currently a virus is commonly used for that. The virus “infects” the target area with the healthy gene and so the cells can produce functioning proteins again. The genes can also be directly introduced to the target cells; this can only used in some tissues though. Also an artificial

Description Diagram Attachment Virus binds to a specific receptor on the host cell surface. Penetration Viral nucleic acid enters the cell. Synthesis of new components. Viral nucleic acid takes over control of the cell metabolism stopping cell’s normal nucleic acid and protein synthesis. Viral nucleic acid is replicated using nucleotides from the host cell. Protein coats are manufactured using the amino acids of the host cell. Assembly Whole virus particles are made when the nucleic

CU254 Causes and Spread of Infection 1.1Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 1.2 Identify

The Krippen Virus is... elegant.” -Robert Neville A virus breaks out in “I Am Legend”‚ virtually wiping out the human race‚ leaving only a select few to return order to the world. Instead of being contractible through contact‚ in “The Stand”‚ the strain of influenza is an airborne virus. This epidemic wipes out over 99% of the earth’s population‚ sparing a limited number of immune survivors that

At times we can take the smallest things for granted. Can you imagine having difficulties breathing? There are several things in the air that can affect the human body respiratory system. The Respiratory System is the system in the body that deals with supplying the blood with oxygen so that the blood can deliver oxygen to all parts of the body. The respiratory system does this through breathing. There are several diseases that can attack the respiratory system; I will discuss how Influenza affects

The virus cells are injected with the DNA intended to help the patient. The viruses are also given the capacity to recognize target cells. When the modified virus

What is the difference between HSV 1 and 2? HSV-1 most often causes oral herpes and HSV-2 typically causes genital herpes. According to Plan Parenthood‚ HSV-1 (oral herpes) is present in more than half of American adults and 1 in 6 is infected with HSV-2 (genital herpes). Symptoms HSV-1: Lesions knowns as cold sores or fever blister are located on or near the mouth. Sometimes they can be found in the mouth and usually only happen the first time HSV-1 symptoms show up. Now‚ don’t confuse this with
