Denisova cave
Denisova cave entrance in the Altai Mountains of Siberia, Russia where the bones were found from which DNA was sequenced (Copyright (C) 2010, Johannes Krause)

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.
