Abstract:
:The genomic DNA organisation patterns of four sauropsidian species, namely Python reticularis, Caiman crocodilus, Terrapene carolina triungius and Columba livia domestica were investigated by reassociation of short and long DNA fragments, by hyperchromicity measurements of reannealed fragments and by length estimations of S1-nuclease resistant repetitive duplexes. While the genomic DNA of the three reptilian species shows a short period interspersion pattern, the genome of the avian species is organised in a long period interspersion pattern apparently typical for birds. These findings are discussed in view of the close phylogenetic relationships of birds and reptiles, and also with regard to a possible relationship between the extent of sequence interspersion and genome size.
