Homology

Similarity in the sequence of monomers which make up different polymers; e.g. similarity in the base sequence of two different DNA or RNA molecules.

Homology

• (n.) The quality of being homologous; correspondence; relation; as, the homologyof similar polygons. • (n.) The correspondence or resemblance of substances belonging to the same type or series; a similarity of composition varying by a small, regular difference, and usually attended by a regular variation in physical properties; as, ther...

Homology

[anthropology] In anthropology and archaeology, homology is a type of analogy whereby two human beliefs, practices or artifacts are separated by time but share similarities due to genetic or historical connections. Specifically in anthropology, a homology is a structure that is shared through descent from a common ancestor. The concept was ...

Homology

[biology] In the context of biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different species. A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Evolutionary theory explains the existence of homologous structures adapted to diffe...

Homology

[chemistry] In chemistry, homology refers to the appearance of homologues. A homologue (also spelled as homolog) is a compound belonging to a series of compounds differing from each other by a repeating unit, such as a methylene bridge −{chem|CH|2}−, a peptide residue, etc. A homolog is a special case of an analog. Examples are alkanes ...

Homology

[mathematics] in analogy with the n-th homology group. == Types of homology == The different types of homology theory arise from functors mapping from various categories of mathematical objects to the category of chain complexes. In each case the composition of the functor from objects to chain complexes and the functor from chain complexes...

[psychology] Homology in psychology, like homology in biology, refers to a relationship between characteristics that reflects the characteristics` origins in either evolution or development. Homologous behaviors can theoretically be of at least two different varieties. As with homologous anatomical characteristics, behaviors present in diff...

[sociology] Homologies are `structural `resonances`...between the different elements making up a socio-cultural whole.` (Middleton 1990, p. 9) Examples include Alan Lomax`s cantometrics, which: Richard Middleton (1990, p. 9-10) argues that `such theories always end up in some kind of reductionism - `upwards`, into an idealist cultural spiri...

homology

A way of attaching Abelian groups, or more elaborate algebraic objects, to a topological space so as to obtain algebraic invariants. In a sense, it detects the presence of 'holes' of various dimensions in the space. The methods developed to handle this led to what is now called homological algebra, ...

homology

Two structures are considered homologous when they are inherited from a common ancestor which possessed the structure. This may be difficult to determine when the structure has been modified through descent.
