title: Subunit organization of chromatin from trypanosoma cruzi sensitive and resistant to ethidium bromide.
abstract: The chromatin from Trypanosoma cruzi has been analysed from a nuclear preparation after digestion with micrococcal nuclease. The DNA repeat length is found to be equivalent to 185 +/- 5 base pairs. The organization of chromatin in T. cruzi has been compared with that of sensitive trypanosomes treated with ethidium bromide and trypanosomes resistant to ethidium bromide. No differences were found.
