bacteriophage with rNA genome that codes for the enzyme RNA synthetase and for the coat protein, a protein to which the RNA is attached and that is involved in attachment to the bacterium.
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 -- Virus which infects and destroys a bacterial host. Some phages, however, will incorporate their DNA into that of their host, and remain dormant for an extended period.
bacteriophage

A virus that parasitizes a bacterial cell.

Bacteriophage: A virus whose host is a bacterium. Also called phage.
Base: See nitrogenous base.
Bacteriophage (or simply Phage)
A virus that infects a bacterium.
Bacteriostatic
A condition which prevents the growth of bacteria without killing them.
Bacteriophage: See phage.
Base pair (bp): Two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds. Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs.
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.
bacteriophages
a type of virus that infects bacteria. Infection with a bacteriophage may or may not lead to the death of the bacterium, depending on the phage and sometimes on conditions. Each bacteriophage is specific to one form of bacterium.

Bacteriophage: A virus that infects a bacterium.
Balanced lethal: Lethal mutations in different genes on the same pair of chromosomes that remain in repulsion because of close linkage or crossover suppression.
Bacteriophages
Bacteriophages are viruses that infect bacteria. They are not surrounded by a membrane as the animal-infecting viruses discussed above.

BACTERIOPHAGE - A virus that infects bacteria; often simply called a phage. The phages which are most often used in molecular biology are the E. coli viruses lambda, M13 and T7.
Bacteriophage lambda: A virus which infects E. coli , and which is often used in molecular genetics experiments as a vector, or cloning vehicle.
Some bacteriophages contribute to the virulence of bacterial infections. Certain phages can enter an alternate life cycle called lysogeny. In this cycle, all the virus's DNA becomes integrated into the genome of the host bacterium.
bacteriophages Viruses that attack and kill bacterial cells; composed only of DNA and protein. PICTURE
bark The outer layer of the stems of woody plants; composed of an outer layer of dead cells (cork) and an inner layer of phloem.
Other bacteriophages can infect a host and insert their DNA into the host DNA. Under certain conditions the viral DNA can detach and direct replication of new virus, eventually killing the host cell.
BacteriophageBacterial virus. Lambda bacteriophage is the basis of many E. coli vectors which are used for cDNA and genomic DNA libraries.
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).
Once the vessel reached steady state they innoculated it with bacteriophage T7. The bacteria are sensitive to infection by T7. Needless to say, T7 grew like mad on the bacteria.
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.
The TAC vector contains the P1 bacteriophage replicon, which maintains the vector in a single copy, and therefore renders foreign DNA fragments stable, in E. coli cells.
One type of vector used to clone DNA fragments (100- to 300-kb insert size; average, 150 kb) in Escherichia coli cells. Based on bacteriophage (a virus) P1 genome.
