Document Summary
The highly repeated fraction (also called tandem repeats ) constitutes anywhere from about 1 to 10 percent of the total dna. These sequences are typically short (a few hundred nucleotides at their longest) and present in clusters in which the given sequence repeats itself over and over again without interruption. A sequence arranged in this end to end manner is said to be into several overlapping categories, including satellite sdnas, minisatellite dnas, and microsatellite dnas. Dna sequence variation than human living on other continents populations because genomes of african populations have had longer to diverge: the argument for african genesis has received support from numerous studies on human dna sequences. Once it became apparent that eukaryotic genomes contain large numbers of copies of short dna sequences, researchers sought to learn where the chromosomes these dna sequences are located in. The ability to locate satellite dna sequences illustrates the analytic power of nucleic acid hybridization.
