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.
