Sanger
454 (single reads)
454 (paired ends)
Features:
* approximately 84-nucleotide DNA fragments * have a ~ 44-mer linker sequence in the middle * flanked by a ~ 20-mer sequence on each side. * The two flanking 20-mers are segments of DNA that were originally located approximately 2.5 kb apart in the genome of interest. * The ordering and orienting of contigs generates scaffolds which provide a high-quality draft sequence of the genome.
Anomalies:
* the linker can appear (tandem,completely/partially) more than once
