Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae of the family Straboviridae. T4 is capable of undergoing only a lytic life cycle and not the lysogenic life cycle. The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates ...
Species: Escherichia virus T4. Strain: Enterobacteria phage T2. Enterobacteria phage T2 is a virus that infects and kills E. coli. It is in the genus Tequatrovirus, and the family Myoviridae. Its genome consists of linear double-stranded DNA, with repeats at either end. The phage is covered by a protective protein coat.
Enterobacteria phage λ ( lambda phage, coliphage λ, officially Escherichia virus Lambda) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli ( E. coli ). It was discovered by Esther Lederberg in 1950. [2] The wild type of this virus has a temperate life cycle that allows it to either reside within the genome of its host through lysogeny or enter into a ...
Scanning thermal microscopy ( SThM) is a type of scanning probe microscopy that maps the local temperature and thermal conductivity of an interface. The probe in a scanning thermal microscope is sensitive to local temperatures – providing a nano-scale thermometer.
Cryogenic electron microscopy ( cryo-EM) is a cryomicroscopy technique applied on samples cooled to cryogenic temperatures. For biological specimens, the structure is preserved by embedding in an environment of vitreous ice. An aqueous sample solution is applied to a grid-mesh and plunge-frozen in liquid ethane or a mixture of liquid ethane and propane. [1] While development of the technique ...
Transmission electron cryomicroscopy ( CryoTEM ), commonly known as cryo-EM, is a form of cryogenic electron microscopy, more specifically a type of transmission electron microscopy (TEM) where the sample is studied at cryogenic temperatures (generally liquid-nitrogen temperatures). [1] Cryo-EM, specifically 3-dimensional electron microscopy ( 3DEM ), is gaining popularity in structural ...
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1107 ahead. Let's start with a few hints.
Acoustic microscopy. Acoustic microscopy is microscopy that employs very high or ultra high frequency ultrasound. Acoustic microscopes operate non-destructively and penetrate most solid materials to make visible images of internal features, including defects such as cracks, delaminations and voids .
