Sequencing of difficult DNA Regions by SAM sequencing.

Nucleotide analogues are used increasingly in medicine and biotechnology to effect DNA sequence change, principally via clastogenic and transcriptional effects. This article, however, discusses the use of mutagenic nucleotide analogues to improve the sequencing of recalcitrant and repetitive DNA motifs. Guidance in the technical and practical approaches that support use of this approach with different DNA sequencing technologies is provided, including for high-throughput technologies.
