What disease does T7 cause?
Bacteriophage T7 (or the T7 phage) is a bacteriophage, a virus that infects bacteria. It infects most strains of Escherichia coli and relies on these hosts to propagate. Bacteriophage T7 has a lytic life cycle, meaning that it destroys the cell it infects….T7 phage.

Is there a T7 virus vaccine?
T7 phage may be potentially useful as a delivery vector for DNA vaccine transfer. The surface display capability of T7 phage also enlarge the use in vaccine design, for it can surface display antigen epitope and carry DNA vaccine within one particles.
What does the T7 virus do?
T7 viruses are used extensively in modern molecular biology research. Scientists can manipulate the genomes and proteins of these viruses to study gene expression, protein interactions, and more.
Does T7 affect bacteria?
T7 infects Escherichia coli Gram-negative bacteria.
What organ is T7?
Larger than your T6 vertebra, the T7 houses the nerve which provides messages between your brain, your pancreas, your spleen and your duodenum. It’s a strong central vertebra, and connects directly to the ribcage.
What are the symptoms of T7?
In general, a patient with a fractured T7 would experience pain when moving, and have difficulty standing for long periods. Patients with associated rib fractures may sometimes even have pain with breathing (particularly when taking big breaths).
What is the cellular receptor of bacteriophage T7?
In E. coli B the primary receptor for T7 is the R-core portion of the lipopolysaccharide (LPS) of the outer membrane; in smooth strains the R-core is inaccessible to the phage gp17 tail fibers, which specify the adsorption host-range. The precise adsorption component may be different on E.
What does T7 do to E coli?
T7 RNA polymerase is a very active enzyme: it synthesizes RNA at a rate several times that of E. coli RNA polymerase and it terminates transcription less frequently; in fact, its transcription can circumnavigate a plasmid, resulting in RNA several times the plasmid length in size.
Which viruses have a narrow range?
Microcystis viruses Ma-LMM01 and MaMV-DC are Myoviridae family members with very narrow host ranges, and they are known only to infect M. aeruginosa strains NIES-298 (12) and FACHB-524 (13) among the tested strains, respectively.
What do you need to know about the T7 phage?
T7 phage. Jump to navigation Jump to search. Bacteriophage T7 (or the T7 phage) is a bacteriophage, a virus that infects susceptible bacterial cells, that is composed of DNA and infects most strains of Escherichia coli. Bacteriophage T7 has a lytic life cycle and several properties that make it an ideal phage for experimentation.
How does phage T7 repair a double strand of DNA?
T7 DNA polymerase, assisted by E. coli thioredoxin, performs both leading and lagging-strand DNA synthesis . In phage T7, DNA double-strand breaks are likely repaired by insertion of a patch of donor DNA into a gap at the break site.
What is the function of the sliding clamp in phage T7?
The sliding clamp functions to hold the polymerase onto the DNA, which increases the rate of synthesis. Phage T7 has the simplest known DNA replisome, consisting of a helicase and primase that reside in a single polypeptide chain that forms a hexamer in the presence of DNA and ATP or dTTP.
What is the function of thioredoxin in T7 phage?
T7 polymerase uses E. coli ‘s endogenous thioredoxin, a REDOX protein, as a sliding clamp during phage DNA replication (though thioredoxin normally has a different function). The sliding clamp functions to hold the polymerase onto the DNA, which increases the rate of synthesis.
