For analysis of patterns and sequences in the human genome (perhaps using the SNP database extraction tool on this website), you may need a control - any number of random samples of the human genome of a particular size. Given the information on chromosome nucleotide accession numbers provided by NCBI, this tool will gather the sequences you want.
To prevent overloading or timing out the requests via this webform, sequences are obtained one at a time, by clicking the button below. Sometimes, there will be an error processing the request, or the region queried will return a sequence of all N's - if this happens, you will get an alert but then can try again.
