contig

A chromosome map showing the locations of those regions of a chromosome where contiguous DNA segments overlap. Contig maps are important because they provide the ability to study a complete, and often large segment of the genome by examining a series of overlapping clones which then provide an unbroken succession of information about that region. See also chromosome, cloning, gene, genome

Group of cloned (copied) pieces of DNA representing overlapping regions of a particular chromosome.

A set of overlapping cloned DNA fragments that can be assembled to represent a defined region of the chromosome or genome from which they were obtained. Contig definition is a necessary step for assembling whole genome sequences.
