title: [Cloning of segments of the Drosophila melanogaster genome using artificial chromosomes of the yeast Saccharomyces cerevisiae].
abstract: A partial genomic library from the Batumi L stock of Drosophila melanogaster was constructed using yeast artificial chromosomes as vectors. The DNA was restricted by Not1 and large fragments were inserted into the YAC5 vector. The size of cloned DNA varied from 90 to 500 kb. 48 random clones were characterized by in situ hybridization to the Batumi L polytene salivary gland chromosome. Single euchromatic sites of hybridization were detected for 27 clones; 11 clones revealed the main euchromatic hybridization site and several additional sites scattered along the chromosomes; 8 clones carried repeats which hybridized to chromocenter and other chromosomal sites; clones with 500 and 90 kb inserts originated from the Y chromosomes and nucleolus, respectively. The library is enriched by the repeated sequences related to the b-heterochromatin.
