The principle of mutability is the notion that any physical property which appears to follow a conservation law may undergo some physical process that violates its conservation. [ 1 ] [ 2 ] [ 3 ] John Archibald Wheeler offered this speculative principle after Stephen Hawking predicted the evaporation of black holes which violates baryon number ...
Spontaneous mutations occur with non-zero probability even given a healthy, uncontaminated cell. Naturally occurring oxidative DNA damage is estimated to occur 10,000 times per cell per day in humans and 100,000 times per cell per day in rats. [34]
In addition to these counts, data on the mutability and the frequency of the amino acids was obtained. [6] [7] The mutability of an amino acid is the ratio of the number of mutations it is involved in and the number of times it occurs in an alignment. [7] Mutability measures how likely an amino acid is to mutate acceptably.
"Mutability" is a poem by Percy Bysshe Shelley which appeared in the 1816 collection Alastor, or The Spirit of Solitude: And Other Poems. Half of the poem is quoted in his wife Mary Shelley 's novel Frankenstein; or, The Modern Prometheus (1818) although his authorship is not acknowledged, while the 1816 poem by Leigh Hunt is acknowledged with ...
Prior to Charles Darwin, most naturalists were saltationists, [a] believing that species evolved and that speciation took place in sudden jumps. [4] Jean-Baptiste Lamarck was a gradualist but similar to other scientists of the period had written that saltational evolution was possible.
For example, the mutability of art is a core principle of Arte Povera, a contemporaneous movement that emerged in Italy which holds that works of art "should not be seen as fixed entities", but as objects of change and movement to "include time and space in a new manner. At stake is the issue of transferring the phenomenology of human ...
The two possibilities tested by the Luria–Delbrück experiment. (A) If mutations are induced by the media, roughly the same number of mutants are expected to appear on each plate.
These include Gini's index of mutability, [13] Simpson's measure of diversity, [14] Bachi's index of linguistic homogeneity, [15] Mueller and Schuessler's index of qualitative variation, [16] Gibbs and Martin's index of industry diversification, [17] Lieberson's index. [18] and Blau's index in sociology, psychology and management studies. [19]
