Genomic and phylogenetic evidence of VIPER retrotransposon domestication in Trypanosomatids
(Fundação Oswaldo Cruz, 2017)
Molecular characterization of SSS139, a new satellite DNA family in sibling species of the Drosophila buzzatii cluster
(Sociedade Brasileira de Genética, 2008)
We characterized sequences of a novel SSS139 RsaI satellite DNA family in Drosophila gouveai and Drosophila seriema, two members of the Drosophila buzzatii cluster (D. repleta group). The sequences were AT-rich (69%) with ...
Whydration effects on DNA double helix stability modulates ligand binding to natural DNA in response to changes in water activity
(Cellular & Molecular Biology, 2001-07-01)
In this work we present evidence that water molecules are actively involved on the control of binding affinity and binding site discrimination of a drug to natural DNA. In a previous study, the effect of water activity ...

Successful application of ancient DNA extraction and library construction protocols to museum wet collection specimens
(2021-10-01)
Millions of scientific specimens are housed in museum collections, a large part of which are fluid preserved. The use of formaldehyde as fixative and subsequent storage in ethanol is especially common in ichthyology and ...
Nuclear DNA content determination in Characiformes fish (Teleostei, Ostariophysi) from the Neotropical region
(Sociedade Brasileira de Genética, 2002-01-01)
In the present study, nuclear DNA content was analyzed in 53 species of Characiformes fish from the Neotropical region. Diploid number ranged from 2n = 48 in Astyanax fasciatus, Gymnocorymbus ternetzi and Hyphessobrycon ...

Molecular characterization of Acidithiobacillus ferrooxidans and A-thiooxidans strains isolated from mine wastes in Brazil
(Springer, 2001-10-01)
Nineteen strains of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans, including 12 strains isolated from coal, copper, gold and uranium mines in Brazil, strains isolated from similar sources in other countries ...
Chromosomal Mapping of Repetitive DNA Sequences in the Genus Bryconamericus (Characidae) and DNA Barcoding to Differentiate Populations
(Mary Ann Liebert, Inc, 2017-06-01)
The mapping of repetitive DNA sites by fluorescence in situ hybridization has been widely used for karyotype studies in different species of fish, especially when dealing with related species or even genera presenting high ...
