mapping

 [map´ing]
the creation on a flat surface of a representation of an area, showing the relative position of various features.
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.

genetic mapping

1. The process of determining the location of the genes for various characteristics and diseases in the chromosomes.
2. The determination of the sequence of bases in the chromosomes corresponding to the genes. The human GENOME mapping project is now under way and is hoped to be completed by the beginning of the 21st Century.

The DNA molecules are useful for specifying a gene product in cells, either as a promoter or as a protein coding sequence or as an UTR or as a 3' termination sequence, and are also useful in controlling the behavior of a gene in the chromosome, in controlling the expression of a gene or as tools for genetic mapping, recognizing or isolating identical or related DNA fragments, or identification of a particular individual organism, or for clustering of a group of organisms with a common trait.
