title: Genome mapping: cDNA approaches.
abstract: Clones of cDNAs have several practical advantages as start points for making physical maps of genomes: they are mainly single copy; they expand the map because of the introns in the genomic version of the gene; and they are conserved between species. They also address biologically important regions of the genome. Sequence information helps to identify new gene functions.
