 <P>
 Bacterial artificial chromosomes (BACs) are a key part of many
 large-scale sequencing projects.  A BAC typically consists of 50 - 300 kb of
 DNA.  During the early phase of a sequencing project, it is common
 to sequence a single read (approximately 500 bases) off each end of
 a large number of BACs.  Later on in the project, these BAC end reads
 can be mapped to the genome sequence.</P>
 <P>
 These BAC end pairs can be useful for validating the assembly over
 relatively long ranges.  In some cases, the BACs are useful biological
 reagents.  This track can also be used for determining which BAC
 contains a given gene, useful information for certain wet lab experiments.</P>
