1 the layer of air near the earth is cooler than an overlying layer
2 abnormal condition in which an organ is turned inward or inside out (as when the upper part of the uterus is pulled into the cervical canal after childbirth)
3 a chemical process in which the direction of optical rotation of a substance is reversed from dextrorotatory to levorotary or vice versa
4 (genetics) a kind of mutation in which the order of the genes in a section of a chromosome is reversed
5 the reversal of the normal order of words [syn: anastrophe]
6 (counterpoint) a variation of a melody or part in which ll ascending intervals are replaced by descending intervals and vice versa
7 a term formerly used to mean taking on the gender role of the opposite sex [syn: sexual inversion]
8 turning upside down; setting on end [syn: upending]
- Rhymes: -ɜː(r)ʒən
- The move of one pitch in an interval or chord up or down an octave
- The reversal of an interval
- The reversal of the pitch contour
- The reversal of a pitch class succesion such as a melody or contrapuntal line
- Subtraction of pitch classes in a set from twelve which maps intervals onto their complements with respect to 0 and preserves interval classes, symbolized IX where X is the transposition which is inverted (DeLone et. al. (Eds.), 1975, chap. 6).
- a segment of DNA in the context of a chromosome that is reversed in orientation relative to a reference karyotype or genome
- (Weather). An increase of air temperature with increase in altitude (the ground being colder than the surrounding air). When an inversion exists, there are no convection currents and wind speeds are below 5 knots. The atmosphere is stable and normally is considered the most favorable state for ground release of chemical agents.
- Deviation from
standard word order by putting the predicate before the subject. It
takes place in questions with auxiliary
verbs and in normal, affirmative clauses beginning with a
negative particle, for the purpose of emphasis.
- (with an auxiliary verb) Inversion takes place in the sentence
'Is she here?' — 'is', the predicate, is before 'she',
- (for the purpose of emphasis) Inversion takes place in the sentence 'Never have I done that.' — 'have', the predicate, is before 'I', the subject, due to 'never' being the first word of the sentence.
- (with an auxiliary verb) Inversion takes place in the sentence 'Is she here?' — 'is', the predicate, is before 'she', the subject.
- an outdated term for homosexuality, particularly popular in early psychoanalysis

- Freeman et al., "Copy number variation: New insights into genome diversity" Genome Res 2006; 16: 949-61. — "DNA copy number variation has long been associated with specific chromosomal rearrangements and genomic disorders, but its ubiquity in mammalian genomes was not fully realized until recently. Although our understanding of the extent of this variation is still developing, it seems likely that, at least in humans, copy number variants (CNVs) account for a substantial amount of genetic variation."
