Phage is a virus that consists of a protein coat that surrounds the core of DNA. When phage DNA enters the host cell it directs phage reproduction. DNA is the molecule that is responsibility for heredity. In this experiment‚ phage was added to E.coli in a radioactive medium. Phages were used to demonstrate that DNA is the genetic material. The DNA molecule is surrounded by a protein coat. So‚ when phages infect bacteria‚ they will attach to the surface of the bacterium. When this happens‚ they inject

or viruses causing physical illness such as flu. It seems though that infection can also give a rise to mental illness. Flu has been linked to schizophrenia. Recent research shows that schizophrenia cases have been linked with exposure to the flu virus in the womb during the first trimester. The third factor is biochemistry. Neurotransmitters are thought to be out of balance in the nervous system of individuals with certain psychological disorders. For example schizophrenia has been associated with

DNA or RNA‚ viruses‚ unlike bacteria are not self-sufficient and need a ‘host’ in order to reproduce‚ for example: ‘Human Body’. When a virus enters the body‚ it enters some certain cells and takes over making them the new ‘host cell’ which makes the parts the virus needs to reproduce‚ the cells are eventually destroyed through this process. The most common virus is the ‘common cold’ which has no cure. Fungi – Mould‚ yeast and mushrooms are all types of fungi. Fungi live in air‚ water‚ soil and on

capable of fighting off most bacterial infections so they can mainly be treated with antibiotics. A viral infection is a type of infection by a virus. It is one in which it is spreaded by a virus that is pathogenic to human beings. They are much smaller than bacteria and it is much more difficult to kill a virus than it is to kill bacteria. A virus can’t grow or exist without any host cells. It could cause illnesses as minor as the common cold or as severe as AIDS. Unlike Bacterial Infections

evolution of bacteria is to somehow replace the bacteria’s DNA/RNA polymerase with one that is much better and accurate. This might fool the bacteria/virus into thinking this is a positive change and they might keep it which eventually will make them less susceptible to mutations and dramatically slow down their rate of evolution. However‚ the virus might not accept this as a positive change and natural selection may pick this off right away. Evolution is a very hard if not impossible force of nature

Approach Considerations Treatment decisions in children with pneumonia are dictated based on the likely etiology of the infectious organism and the age and clinical status of the patient. Antibiotic administration must be targeted to the likely organism‚ bearing in mind the age of the patient‚ the history of exposure‚ the possibility of resistance (which may vary‚ depending on local resistance patterns)‚ and other pertinent history (see Etiology and Clinical Presentation). After initiating therapy

Is gene therapy the most effective way to treat depression? What really is depression? The term ‘depression’ can be defined in two different ways: 1. Severe despondency and dejection‚ accompanied by feelings of hopelessness and inadequacy. 2. A condition of mental disturbance‚ typically with lack of energy and difficulty in maintaining concentration or interest in life.1 Majority of people believe that depression is somewhat trivial and is not regarded as a genuine health condition‚ but

This perpetrator who remains faceless is known as the influenza virus. The influenza virus commonly known as the flu is a contagious viral infection that invades its victim’s body via the nose and mouth affecting the respiratory system of the individual. It spreads by respiratory droplets through coughing and sneezing.

Ebola By: Fahd Seddiki and Conrad Womelsdorf Discovery of Ebola The discovery of Ebola was made after an epidemic of this virus was spread throughout Sub-Sahara Africa. The actual discovery was made by a native by the name of DR. Ngoy Mushola. He discovered it in 1976 after the epidemic hit his country. The first case of Ebola was called Ebola Zaire. It was discovered in Zaire hence the name. The second discovery of Ebola was called Ebola Sudan; also it was discovered in Sudan. Although
