Bacteriophage P2 was first isolated by G. Bertani from the Lisbonne and Carrère strain of E. coli in 1951. [3] Since that time, a large number of P2-like prophages (e.g. 186, HP1, HK239, and WΦ) have been isolated that shared characters such as host range, serological relatedness and inability to recombine with phage λ, and they seemed to be quite common in E. coli populations as about 30% ...
Phosphatidylinositol 4,5-bisphosphate or PtdIns(4,5)P 2, also known simply as PIP 2 or PI(4,5)P 2, is a minor phospholipid component of cell membranes. PtdIns(4,5)P 2 is enriched at the plasma membrane where it is a substrate for a number of important signaling proteins. [1]
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
A distinguishing feature was that the nasal incision was retracted to the P2-P3 premolars. [17] The back of the skull was low and narrow, without the large lambdoid crests at the top and along the sagittal crest, which are otherwise found in horned and tusked animals that need strong muscles to push and fight. It also had a deep pit for the ...
Buffer P2 is a lysis buffer solution produced by Qiagen.It contains 1% sodium dodecyl sulfate (SDS) (w/v) to puncture holes in cellular membranes, and 200mM NaOH.It is used in conjunction with other resuspension buffers and lysis buffers to release DNA from cells, often as part of the alkaline lysis method of purifying plasmid DNA from bacterial cell culture.
Please take a look at Wikipedia:The answer to life, the universe, and everything and Wikipedia: What Wikipedia is not for some general information about Wikipedia, and then take a look at Wikipedia:Autobiography and Wikipedia:An article about yourself isn't necessarily a good thing if my guess is correct and you'd like to try and create a ...
Zinc and chloride are essential for life. Zn 2+ is a component of several enzymes, e.g., carboxypeptidase and carbonic anhydrase. Thus, aqueous solutions of zinc chlorides are rarely problematic as an acute poison. [5] Anhydrous zinc chloride is however an aggressive Lewis acid as it can burn skin and other tissues.
The Hitchhiker's Guide to the Galaxy is a comic science fiction series created by Douglas Adams that has become popular among fans of the genre and members of the scientific community. Phrases from it are widely recognised and often used in reference to, but outside the context of, the source material.
