ABSTRACT

Macronuclear DNAs from three related hypotrichous ciliated protozoans were compared by agarose gel electrophoresis. Each was shown to be composed of DNA duplexes that yielded a unique pattern of bands overlying a continuous distribution of DNA sizes ranging from ∼400 bp to ∼20,000 bp. By EM, the number average molecular sizes for doublestranded DNA were 2,200 bp for Oxytricha sp., 2,514 bp for Stylonychia pustulata and 1,836 bp for Euplotes aediculatus. Contrary to previous reports we present evidence that the macronuclear DNAs in each of these three organisms lack single-stranded interruptions. More... »
