Industry:Archaeology
A process to identify adjacent clones in a genomic library. In chromosome walking, a piece of DNA is used to probe a genomic library to find an overlapping clone; then a piece of that clone is used as a probe to screen the library again for an overlapping clone; and so on.
Industry:Archaeology
An enzyme-catalyzed, light-independent process of repair of ultraviolet-light-induced thymine dimers in DNA that involves removal of the dimers and synthesis of a new piece of DNA complementary to the undamaged strand.
Industry:Archaeology
In non-market societies, prestige valuables and ordinary commodities were often exchanged quite separately, i.e., valuables were exchanged against valuables in prestige transactions, while commodities were exchanged against commodities with much less ceremony, in mutally profitable barter transactions. These separate systems are termed spheres of exchange.

This method aspires to the direct dating of rock carvings and engravings, and is potentially applicable to Paleolithic artifacts with a strong patina caused by exposure to desert dust. It depends on the principle that cations of certain elements are more soluble than others; they leach out of rock varnish moe rapidly than the less soluble elements, and their concentration decreases with time.
Industry:Archaeology
A genetic recombination that occurs following the rare pairing of homologs during mitosis of a diploid cell.
