Patterns of DNase I sensitivity in the chromosomes of the ant Tapinoma nigerrimum (Hymenoptera, Formicidae).
We have analysed the patterns of DNase I/nick translation in the chromosomes of Tapinoma nigerrimum. The results show a non-uniform DNase I sensitivity in different chromosome domains. The hypersensitivity appears to be specially concentrated at both the NOR and the distal regions. The resemblance to and differences from the situation in other animal species, in which active genes are DNase I hypersensitive, are discussed.
