RNA polymerase II ( RNAP II and Pol II) is a multiprotein complex that transcribes DNA into precursors of messenger RNA (mRNA) and most small nuclear RNA (snRNA) and microRNA. [ 1][ 2] It is one of the three RNAP enzymes found in the nucleus of eukaryotic cells. [ 3] A 550 kDa complex of 12 subunits, RNAP II is the most studied type of RNA ...
A biomolecule or biological molecule is loosely defined as a molecule produced by a living organism and essential to one or more typically biological processes. [ 1] Biomolecules include large macromolecules such as proteins, carbohydrates, lipids, and nucleic acids, as well as small molecules such as vitamins and hormones.
Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [ 1]
Evolution is a light which illuminates all facts, a curve that all lines must follow. (p. 219 of The Phenomenon of Man) The phrase "nothing in biology makes sense except in the light of evolution" has come into common use by those opposing creationism or its variant called intelligent design. [ 5][ 8] While the essay argues (following de ...
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules and to direct their replication within host organisms. [ 1] The use of the word cloning refers to the fact that the method involves the replication of one molecule to produce a population of cells with identical DNA molecules.
Mediator is a multiprotein complex that functions as a transcriptional coactivator in all eukaryotes. It was discovered in 1990 in the lab of Roger D. Kornberg, recipient of the 2006 Nobel Prize in Chemistry. [ 1][ 2] Mediator [ a] complexes interact with transcription factors and RNA polymerase II. The main function of mediator complexes is to ...
Automated analyser. An automated analyser is a medical laboratory instrument designed to measure various substances and other characteristics in a number of biological samples quickly, with minimal human assistance. These measured properties of blood and other fluids may be useful in the diagnosis of disease. Roche Cobas 6000.
