Paired End reads:

 * approximately 84-nucleotide DNA fragments 
 * have a 44-mer adaptor 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.
