mature phages. One of the phages has the incorporated bacterial DNA‚ that one are called defective virus. This defective virus infected other bacterium but instead of injecting viral nucleic acid it is injecting bacterial DNA. The new infected bacterium will recombine its own DNA with the received bacterial DNA from the phages. The virus will not replicate or lyses the cell because it is a defective virus. The bacterium survives and can use this new genetic material that was incorporated into its chromosome

In 1918‚ there was a flu pandemic. A pandemic is an infectious transmissible disease that has spread throughout the human populations. While this

became a professor at Harvard University Medical School and‚ by 1924‚ was a professor of Bacteriology and Public Health at Washington University in St. Louis. While Rife was acquiring the technical skills and instruments he needed to isolate the cancer virus‚ Dr. Kendall was developing a protein culture medium for cultivation of the typhoid Bacillus. The typhoid Bacillus was usually large enough to be viewed through ordinary research microscopes of the time. However‚ when he used his Medium K‚ this bacterium

The Ebola Virus History of‚ Occurrences‚ and Effects of Ebola‚ a virus which acquires its name from the Ebola River (located in Zaire‚ Africa)‚ first emerged in September 1976‚ when it erupted simultaneously in 55 villages near the headwaters of the river. It seemed to come out of nowhere‚ and resulted in the deaths of nine out of every ten victims. Although it originated over 20 years ago‚ it still remains as a fear among African citizens‚ where the virus has reappeared occasionally in parts

follows the storyline of two characters in a post apocalyptic world. “What is the disaster?” you ask. A zombie outbreak‚ once again. However‚ this one has a new spin on things to keep it fresh: it is based on a real infection called cordyceps created by plants‚ using fungus spores. The spores infect ants and other bugs that may be threatening the plant ecosystem. The Last of Us is a fantastic zombie survival game with a realistic‚ linear storyline. Originally the game came out for the Playstation 3

The Ebola Virus A virus is an ultramicroscopic infectious organism that‚ having no independent metabolic activity‚ can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid‚ either RNA or DNA‚ surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication‚ and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that

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
