title: Random subcloning of sonicated DNA: application to shotgun DNA sequence analysis.
abstract: A method for producing random subclones using sonication to fragment the DNA is presented. The sonication is combined with enzymatic repair of the fragment ends and a rigorous size fractionation step to prepare subclones of relatively homogeneous and specific size. Under some conditions sonication is shown to shear A + T-rich sequences preferentially, although under most conditions it will create a random subclone library. The use of these subclone libraries for an improved "shotgun" DNA sequencing strategy is tested on a 17.2-kb (kilobase) fragment of Epstein-Barr virus.
