Details from genomic library record for Caltech Human BAC library D, which has 5 segments. Clones in all segments are derived from the same DNA source (A) and were cloned into the same vector (B). Clones in the 5th segment were cloned into a different restriction enzyme site (C) and the average insert sizes for clones in the 5 segments are all different (D).
