Description
The Denisova Sequence track shows
high-coverage sequence reads from an archaic Denisovan individual
mapped to the human genome reference assembly.
The Denisova DNA was extracted from a phalanx bone excavated from
Denisova Cave in the Altai Mountains in southern Siberia.
Methods
A novel single-stranded DNA library preparation method
(Note 2,
supplementary online materials of Meyer, 2012)
was applied to DNA previously extracted from 40mg of bone (Reich, 2010).
Using single-stranded DNA greatly increased the genomic coverage to
30X compared to an earlier 1.9X sequence (Reich, 2010).
Sequence reads were aligned to human sequence Feb. 2009 (GRCh37/hg19)
(downloaded from the
1000 Genomes Project) using the
Burrows-Wheeler Aligner.
