A genomic l i b ra r y of s ingle copy rat DNA was prepared in phage Ml3. Total rat DNA was digested with the res t r i c t i on endonuclease Mbol. Unique Sequence DNA was isolated and l igated in to the Bam HI s i te of the rep l i ca t i ve form of the bacteriophage Ml3 mp7. Single stranded DNA from ind iv idua l recombinant Ml3 mp7 clones was digested with Sau 3A, which p re fe ren t i a l l y removes the rat DNA insert , label led with 32p by polynucleotide kinase, and hybridized to adult brain to ta l RNA. Clones containing sequences homologous to brain t ranscr ip ts were determined by a var ia t ion of the t ranscr ip t ion mapping technique. About 20% of these s ingle stranded clones were homologous to adult rat brain RNA, which agrees with our ea r l i e r RNA complexity data (Chikaraishi et a l , Cell 13, 1978). Also as expected, these clones correspond to rare brain t ranscr ip ts (O.05-1~opy per c e l l ) . These sequences were fu r ther characterized in terms of t ranscr ip t ion in heterologous tissues and in new born brain. At least two of the clones are spec i f i ca l l y transcribed in brain. The t ranscr ip t ion patterns of these cloned DNA fragments may reveal developmental patterns of gene expression.
