The labeled cos end is used as a single reference point to arrange clones in an ordered array for mapping.
Complete cleavage at the cos site in the target DNA is not required because uncleaved cos sites will bactetiofago hybridize with the cosoligonucleotides. In addition, Lambda Terminase cleaves vectors containing the cos site; i. Linearized cosmids give much higher efficiencies in in vitro lambda packaging systems or transfection into animal cells.
A bacteriophage capable of lysogenization, i. A bacterium whose chromosome carries a largely inactive phage genome.
In this state the virus is called a provirus or prophage. Is a filamentous bacteriophage composed of circular single stranded DNA ssDNA which is nucleotides long encapsulated in approximately copies of the major coat protein P8, and capped with 5 copies of two different minor coat proteins P9, P6, P3 on the ends.

The transfer of DNA between two cell genomes by using a vector bacteria, virus. The process removes a certain amount of nitrogen and The ultraviolet light of the sun, the bacteriostatic effect of a long retention time, the bacteriophagic action of more advanced organisms developing naturally makes it possible to divide the bacterial pollution in the effluent Any of the viruses that infect bacterial cells; each has a narrow host range.
The acquisition of new characters e. A virus that infects and replicates within the host cells of bacteria. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells a stage known as the lysogenic phase. But when a dormant virus is stimulated, it enters the lytic phase: The diagram below at right shows a virus that attacks bacteria, known as the lambda bacteriophage, which measures roughly nanometers.
