Intraspecific HindIII restriction fragment length polymorphism (RFLP) for the structural organization of the ribosomal gene cluster was described in Blattella germanica. In this species, homologous chromosomes were shown to contain ribosomal DNA (rDNA) repeats that differ in structure. The pattern of inheritance was determined for various structural(More)
General estimation of ribosomal DNA variation within the Insecta class is presented. It is shown that, using blot-hybridization, one can detect differences in the structure of the ribosomal gene cluster not only between genera within an order, but also between species within a genera, including sibling species. Structure of the ribosomal gene cluster of the(More)
Species-specific characteristics of nuclear ribosomal DNA (rDNA) have been determined for the first time for six insect species of order Blattaria (Insecta, Dictyoptera) with the use of restriction analysis and Southern blotting. Probes containing highly conserved fragments of 18 S- and 28 S-like genes of the ribosomal RNA (rRNA) of Tetrahymena pyriformis(More)
