1. In one, phage replication was wholly dependent on host reproduction.
2. Mnt repressor of phage P22 is homologous to Arc, and also binds its operator as a tetramer.
3. Fischetti says a phage infection and its toxin seem to be mundane; the toxin may be a mere waste product that happens to damage human cells.
4. The phage could be identified and acted as a kind of label, so that bacteria from a single source could be distinguished from others of different origin.
5. Indeed, the specificity of bacteriophages made them useful in identifying particular strains of bacteria, and the procedure called "phage typing" was used for tracing the organism responsible for the spread of an infection in a community.
6. The reaction is performed between one primer designed on the basis of a given protein sequence and a second, which flanks the cloning site in a phage, or plasmid vector.
7. But apparently no one else has looked for a phage that might produce such a toxin.
8. The latter, which may be a plasmid (extrachromosomal molecules of DNA that exist in many bacteria) or a phage (normally a bacterial virus), must be capable of being recognised by the host in order for replication to occur.
9. DNA sequence recognition is achieved largely by hydrogen-bond contacts between the bases and amino-acid side chains located on a -ribbon, a mode of recognition previously hypothesized on the basis of modelling of idealized -strands and DNA, and mutagenesis of the Salmonella phage P22 repressors Arc and Mnt.
10. Traditionally, single stranded DNA for sequencing was obtained by cloning into the M13 bacteriophage system and subsequently purifying phage DNA.
11. The 3.9-kb Eco RI insert of this phage was subcloned into pUC18.
12. The phage, is still unnamed.
13. pPMKO-1 was constructed from phage 3.9 of BALB/c origin.
