A prophage is a temperate phage in its integrated status. Its genome can be integrated into the bacterial host chromosome or exists as an extrachromosomal plasmid. When stress in the host is detected, the phage enters its reproductive cycle.

Bacteriophage Genetics
T2 and its close relative T4 are viruses that infect the bacterium E. coli. The infection ends with destruction (lysis) of the bacterial cell so these viruses are examples of bacteriophages ("bacteria eaters").
Bacteriophage
An E. Coli virus. Commonly used bacteriophases in biology labs are T4, M13 and lambda phages.

Phage
A virus for which the natural host is a bacterial cell. Used as a vector for cloning segments of DNA.
Bacteriophage lambda: A virus which infects E. coli , and which is often used in molecular genetics experiments as a vector, or cloning vehicle.
The bacteriophage becomes attached to the bacteria and its genetic material then enters the bacterial cell. The bacterial cell treats the viral genetic material as if it was its own and subsequently manufactures more virus particles.
Bacteriophage -- a virus whose host is a bacterium; commonly called phage. Barr body -- the condensed single X-chromosome seen in the nuclei of somatic cells of female mammals.

Lytic bacteriophage A phage that replicates in its host and then lyses, or destroys, it.
Bacteriophage (phage or phage particle). A virus that in- fects bacteria. Altered forms are used as vectors for cloning DNA. Bacteriostat. A class of antibiotics that prevents growth of bacterial cells. Bacterium.
Transduction by bacteriophage
for transferring genes from one bacterium to another; this time the transfer is mediated by bacteriophages (bacterial viruses, also called phages) (Fig. 2).
Originally described in bacteria, enhancer trapping was first demonstrated using bacteriophage transposable elements to insert a reporter gene at scattered sites throughout the E. coli genome (Casadaban and Cohen 1979; Bellofatto et al. 1984).
The ones that infect bacteria are called bacteriophage (meaning bacteria eaters).
Bacteriophage are a type of virus that attacks bacteria, the viruses that Delbruck and Luria worked with were those attacking Escherichia coli, a bacterium found in human intestines. Bacteriophages consist of protein coats covering DNA.
The lysogenic cycle occurs when the viral DNA is incorporated into the host DNA as a prophage. When the cell replicates the prophage is passed along as if it were host DNA.
Individual primary recombinant clones (hosted in phage, cosmid, YAC, or other vector) that are placed in two-dimensional arrays in microtiter dishes.
Periodically they assayed cells sampled from the chemostat for resistance to infection by bacteriophage T5 and calculated the density of T5 resistant cells in the culture.
Arrayed library Individual primary recombinant clones (hosted in phage, cosmid, YAC, or other vector) that are placed in two-dimensional arrays in microtiter dishes.
Certain bacterial viruses, such as the T4 bacteriophage, have evolved an elaborate process of infection. The virus has a "tail" which it attaches to the bacterium surface by means of proteinaceous "pins.
Vector: A type of DNA, such as a plasmid or phage that is self-replicating and that can be used to transfer DNA segments among host cells. Also, an insect or other organism that provides a means of dispersal for a disease or parasite.
cosmid A plasmid into which phage lambda cos sites have been inserted. As a result,the plasmid DNA can be packaged in vitro into the phage coat.
In DNA cloning, the plasmid or phage chromosome used to carry the cloned DNA segment.
This enables recombinant molecules to be packaged into lambda phage particles which are able to infect recipient bacteria. It is thus a very efficient way of creating libraries of relatively high molecular weight genomic DNA.
plaque
