| WDMF | wall-defective microbial forms |
| bacteriophage omicron x174 | <microbiology> A bacteriophage (a virus that infects bacteria) which has as its genetic material DNA in single strands instead of the usual double strands. The virus is useful to those who study how DNA replicates. (09 Oct 1997) |
|---|---|
| bacteriophage p1 | An unassigned species of temperate bacteriophage in the family myoviridae which infects e. Coli. It is the largest of the coliphages and consists of double-stranded DNA, terminally redundant, and circularly permuted. (12 Dec 1998) |
| bacteriophage p2 | An unassigned species of temperate bacteriophage in the family myoviridae which infects e. Coli. It consists of linear double-stranded DNA with 19-base sticky ends. (12 Dec 1998) |
| bacteriophage p22 | An unassigned species of temperate bacteriophage in the family podoviridae that infects salmonella species. The genome consists of double-stranded DNA, terminally redundant, and circularly permuted. (12 Dec 1998) |
| bacteriophage phi 6 | Virulent bacteriophage and sole member of the genus cystovirus that infects pseudomonas species. The virion has a segmented genome consisting of three pieces of doubled-stranded DNA and also contains a unique lipid-containing membrane. (12 Dec 1998) |
| bacteriophage phi x 174 | The type species of the genus microvirus. A prototype of the small virulent DNA coliphages, it is composed of a single strand of supercoiled circular DNA, which on infection, is converted to a double-stranded replicative form by a host enzyme. (12 Dec 1998) |
| bacteriophage plaque | A clear circular zone in an otherwise confluent growth of bacteria on an agar surface resulting from bacterial lysis by bacterial viruses. (05 Mar 2000) |
| bacteriophage resistance | Resistance of a bacterial mutant to infection by a bacteriophage to which the parent (wild type) strain is susceptible. (05 Mar 2000) |
| bacteriophage t3 | Bacteriophage in the genus t7-like phages, of the family podoviridae, which is very closely related to bacteriophage t7. (12 Dec 1998) |
| bacteriophage T3 RNA polymerase | <enzyme> Used for the rapid generation of strand-specific RNA molecules that can be used for the identification of genes in hybridization experiments Registry number: EC 2.7.7.- Synonym: t3 RNA polymerase (26 Jun 1999) |
| bacteriophage t4 | <microbiology> A bacteriophage (a virus which infects bacteria) which uses DNA as its genetic material (some viruses use RNA) and is unusually large. (09 Oct 1997) |
| bacteriophage t7 | <microbiology> A bacteriophage (a virus which infects bacteria) that is useful to geneticists because it has a very strong promoter region which strongly encourages transcription of its gene by specific T7 RNA polymerase. Geneticists can take the part with the promoter and attach their own genes of interest to it so that they can control transcription rates of their gene by choosing the amount of the RNA polymerase to put in. (09 Oct 1997) |
| bacteriophage T7 induced DNA polymerase | <enzyme> Complex of two proteins, phage gene 5 protein and E coli thioredoxin Registry number: EC 2.7.7.- Synonym: t7 phage DNA polymerase, sequenase, t7 DNA polymerase, thermo sequenase (26 Jun 1999) |
| bacteriophage typing | A technique of bacterial typing which differentiates between bacteria or strains of bacteria by their susceptibility to one or more bacteriophages. (12 Dec 1998) |
| R17 bacteriophage | 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. (18 Nov 1997) |
