Estudos citogenéticos em espécies da família Paradontidae (Actinopterygii: Characiformes), com enfoque no papel dos DNAs repetitivos na evolução cariotípica do grupo
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Genética Evolutiva e Biologia Molecular - PPGGEvCâmpus São Carlos, 2016-07-01)
Parodontidae is organized in three genera according to their morphological
characteristics: Parodon, Saccodon and Apareiodon. The diploid number is conserved
in this group with 2n=54 chromosomes, with species without ...
TRNA genes affect chromosome structure and function via local effects
(American Society for Microbiology, 2019-04)
The genome is packaged and organized in an ordered, nonrandom manner, and specific chromatin segments contact nuclear substructures to mediate this organization. tRNA genes (tDNAs) are binding sites for transcription factors ...
Sequence analyses and chromosomal distribution of the Tc1/Mariner element in Parodontidae fish (Teleostei: Characiformes)
(Elsevier B.V., 2016-11-30)
Transposable elements are able to move along eukaryotic genomes. They are divided into two classes according to their transposition intermediate: RNA (class I or retrotransposons) or DNA (class II or DNA transposons). Most ...
Robertsonian chromosome polymorphism of Akodon molinae (Rodentia: Sigmodontinae): analysis of trivalents in meiotic prophase
(Sociedad de Biología de Chile, 2001)
Caracterização cromossômica de Diatraea saccharalis (Crambidae, Lepidoptera) com ênfase nos cromossomos sexuais e DNAs repetitivos
(Universidade Estadual Paulista (Unesp), 2021-11-08)
A família de mariposas Crambidae incluem representantes que causam prejuízos econômicos às lavouras agrícolas, como a broca da cana-de-açúcar Diatraea saccharalis. Embora espécies de Crambidae apresentem extensa radiação ...
Long-read single molecule sequencing to resolve tandem gene copies: The Mst77Y region on the drosophila melanogaster Y chromosome
(Genetics Society of America, 2015-04)
The autosomal gene Mst77F of Drosophila melanogaster is essential for male fertility. In 2010, Krsticevic et al. (Genetics 184: 2952307) found 18 Y-linked copies of Mst77F ("Mst77Y"), which collectively account for 20% of ...
Unusual X-Chromosome Inactivation Pattern in Patients with Xp11.23-p11.22 Duplication: Report and Review
(Wiley-Blackwell, 2016)
In females carrying structural rearrangements of an X-chromosome, cells with the best dosage balance are preferentially selected, frequently resulting in a skewed inactivation pattern and amelioration of the phenotype. The ...
Extranuclear structural components that mediate dynamic chromosome movements in yeast meiosis
(Cell Press, 2020-04)
Telomere-led rapid chromosome movements or rapid prophase movements direct fundamental meiotic processes required for successful haploidization of the genome. Critical components of the machinery that generates rapid ...
Chromosomal abnormalities, meiotic behavior and fertility in domestic animals
(2008)
Since the advent of the surface microspreading technique for synaptonemal complex analysis, increasing interest in describing the synapsis patterns of chromosome abnormalities associated with fertility of domestic animals ...
