Evidence of the differentiated structural arrangement of constitutive heterochromatin between two populations of Astyanax scabripinnis (Pisces, Characidae)
The composition of heterochromatin classes along the chromosomes of specimens from two populations of the fish Astyanax scabripinnis was examined using fluorescence banding with GCand AT-DNA specific fluorochromes and fluorescence in situ hybridization (FISH) with an AT-rich satellite DNA (As51) probe. For the pericentromeric heterochromatin blocks neither GC/AT-DNA specific fluorochromes nor t...
متن کاملAstyanax douradilho, a new characid fish from the rio Tramandaí system, southern Brazil (Characiformes: Characidae).
Astyanax douradilho, new species, is described from the rio Tramandaí system, coastal drainage of Rio Grande do Sul State, Brazil. The new species is distinguished from its congeners by possessing 37-39 perforated scales along the lateral line, 3-5 maxillary tricuspid teeth, 22-24 branched anal-fin rays, absence of a conspicuous dark stripe from humeral region to caudal peduncle, two vertically...
متن کاملChromosomal polymorphisms of constitutive heterochromatin and inversions in Drosophila.
A simple technique for preparing mitotic metaphases from a larval ganglion of Drosophila is described. Parallel examination of polytene and metaphase chromosome groups shows that inversion polymorphism in chromosome 3 of D. recticilia from East Maui (Hawaii) manifests a one-to-one correlation with a metaphase karyotype polymorphism due to the presence of an extra heterochromatic portion. These ...
متن کاملAstyanax scabripinnis (Pisces: Characidae) hemoglobins: structure and function.
Electrophoretic patterns of hemoglobins, Root effect, Bohr effect in blood and stripped hemoglobin, Hb-O2 affinity GTP modulation of Astyanax scabripinnis (lambari), caught at three different altitudes in Ribeirão Grande, near Campos do Jordão (São Paulo), are described. All populations showed the same electrophoretic patterns: two cathodal components in starch gel. Normal Bohr effect values we...
متن کاملthe possible association between constitutive heterochromatin polymorphism and human leukemias
objective: polymorphism of the size of heterochromatin region of chromosomes has been well documented in human genome and it consists of dna sequences that are not transcribed. the prime aim of the present study was to evaluate the heterochromatin polymorphism associated with chromosomes in leukemic patients. materials and methods: the study was conducted on 35 consecutive leukemic patients and...
