â30th and Main,â I replied. It was the home of one of Arielleâs book club friends, who Iâd overheard planning to âsurprise her.â Iâd never been there before, but with a little help of the internet I could easily figure out where her friend lived. Fox nodded and switched his car into gear.
bacteriophage. A bacteriophage is a type of virus that infects bacteria. In fact, the word bacteriophage literally means bacteria eater, because bacteriophages destroy their host cells.All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.ventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis. Bacteriophages occasionally remove a portion of their host cells' bacterial DNA during the infection process and then transfer this DNA into the genome of new host cells. This process is known as transduction.
Classification of viruses is defined by host preference, viral morphology, genome type and auxiliary structures such as tails or envelopes. Viral particles outside a host cell (so called virions) are inert entities with a genome surrounded by a protective coat. Viruses that attack bacteria were named âbacteriophages'.The term phage originates from Greek phagein, which translates as âto eat'.MBO J 28, 821â829 (2009); published online 8 April 2009 [PMC free article] [PubMed]. Viruses are minuscule infectious particles composed of a protein coat and a nucleic acid core. They exist in a huge variety of forms and infect practically all living creatures: animals, plants, insects and bacteria.
