RESUMO
Fragments from the DNA of mouse embryos produced by restriction endonucleases HindIII were cloned in pBR322 plasmid and examined for the ability to hybridize in situ with [32P] labeled cDNA synthesized from the polysomal poly(A)+mRNA template. Several of the selected clones were examined for the presence of specific sequences inside the cloned mouse DNA fragments by the blotting procedure of southern [1]. The data obtained indicate that the majority of the cloned mouse DNA fragments contained sequences hybridizing with cDNA, oligo(dT) and double-stranded regions from pre-mRNA. The results of hybridization experiments and double digestion with HindIII+HaeIII endonucleases provide evidence that these sequences could be contiguous in the given restriction DNA fragments.
