[Formation of the genome of the alligator gar Lepisosteus osseus (Ganoidomorpha) genome].
Genome structure of the alligator gar was studied by means of a comparison of reassociation kinetics of short and long DNA fragments, an estimation of hyperchromicity of reassociated repetitive DNA as a function of fragments length, and length estimation of S1-resistant duplexes by gel filtration. It was shown that most of the repeated sequences in the alligator gar DNA are no less than 2000 b.p. long and weakly divergent. Little or no interspersion of unique and short repeated sequences were observed in this genome. No highly divergent repeats were found in the alligator gar genome.
