mapping

 [map´ing]

cardiac mapping an electrophysiological procedure in which electric potentials recorded by electrodes placed directly on the heart are processed to give a two-dimensional display of the origin and path of an electrical impulse as it depolarizes the heart.
genetic mapping determination of the location of genes on chromosomes.
intraoperative lymphatic mapping sentinel node biopsy.

map·ping

(map'ing),
The process of identifying the relative position of sites or elements.

mapping

Etymology: L, mappa, napkin
the process of locating the relative position of genes on a chromosome through the analysis of genetic recombination. Distances between genes in a linkage group are expressed in map units or morgans. Also called chromosome mapping.

mapping

An informatics term of art, used in the context of representing or exchanging data, for connecting items or symbols to codes or concepts.

mapping

The process of determining the order of GENES, and their functions, on the CHROMOSOMES. The human genome project, currently under way, is designed to map the entire collection of the human chromosomes, with incalculable potential benefit to humankind, and a huge increase in responsibility for the application of the knowledge.
