Enterobacteria phage T4. 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.
Multiplicity reactivation (MR) is the process by which multiple viral genomes, each containing inactivating genome damage, interact within an infected cell to form a viable viral genome. MR was originally discovered with phage T4, but was subsequently found in phage λ (as well as in numerous other bacterial and mammalian viruses [20]).
Overview. Thermal radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero. [ 5][ 2] Thermal radiation reflects the conversion of thermal energy into electromagnetic energy. Thermal energy is the kinetic energy of random movements of atoms and molecules in matter.
Thiomargarita namibiensis is a harmless, gram-negative, facultative anaerobic, coccoid bacterium found in the ocean sediments of the continental shelf of Namibia. [ 1] The genus name Thiomargarita means "sulfur pearl." This refers to the appearance of the cells as they contain microscopic sulfur granules that scatter incident light, lending the ...
Frozen section procedure. The frozen section procedure is a pathological laboratory procedure to perform rapid microscopic analysis of a specimen. It is used most often in oncological surgery. [ 1] The technical name for this procedure is cryosection. The microtome device that cold cuts thin blocks of frozen tissue is called a cryotome.
One study concluded the range of total body iodine content in males was 12.1 mg to 25.3 mg, with a mean of 14.6 mg. [77] It is presumed that once thyroid-stimulating hormone is suppressed, the body simply eliminates excess iodine, and as a result, long-term supplementation with high doses of iodine has no additional effect once the body is ...
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.
The microscopic scale (from Ancient Greek μικρός (mikrós) 'small' and σκοπέω (skopéō) 'to look (at); examine, inspect') is the scale of objects and events smaller than those that can easily be seen by the naked eye, requiring a lens or microscope to see them clearly. [ 1] In physics, the microscopic scale is sometimes regarded as ...
