The LEED plaque on a building is a mark of quality and achievement in green building. Leaders across the globe have made LEED the most widely used green building rating system in the world with 1.85 million square feet of construction space certifying every day.
Also known as phage therapy, this method involves the use of a phage to destroy the infective bacteria such as E. coli or salmonella. Bacteriophage is also used in identifying pathogenic bacteria (also called phage typing) in diagnostic laboratories.
Before a virus can reproduce inside a host cell, it must be able to find, recognize and attach to the host cell. Explain how this occurs. Bacteriophages attack bacteria: some kill their host in lyctic cycle; others integrate into host's genome, initiating a lysogenic cycle. In lyctic cycle: exists a viral DNA free in bacterial host cell's cyoplasm that directs production of new viral particles until 1 virus kills cell by lysis.
