Introduction: X-ray diffraction studies have revealed that guanines in a DNA stands may be arranged in quartet and form a structure called G-quadruplexs. Bioinformatics studies suggested the formation of G-quadruplex structure in human crucial genes, including Wilms tumor 1 (WT1). The aim of this study was to in silico analysis of the guanine-rich sequence in the promoter region of the WT1 gene...
Proteins associated with disease and development of the nervous system are thought to contain repetitive, simple sequences. However, genome-wide surveys for simple sequences within proteins have revealed that repetitive peptide sequences are the most frequent shared peptide segments among eukaryotic proteins, including those of Saccharomyces cerevisiae, which has few to no specialized developme...
Genetically modified herbicide resistant (GMHR) crops have transformed weeds management. Today, HR traits are used on >80% of the estimated 134 million hectares of transgenic crops grown annually in 25 countries. Transgenic herbicide traits are five events, including two transgenes code for glyphosate resistance and insensitive 5enolpyruvylshikimate-3-phosphate synthase (EPSPS), the cp4 epsps g...
A corollary of the nearly neutral theory of molecular evolution is that the efficiency of natural selection depends on effective population size. In this study, we evaluated the differences in levels of synonymous polymorphism among Drosophila species and showed that these differences can be explained by differences in effective population size. The differences can have implications for the mol...
BACKGROUND The banana family (Musaceae) includes genetically a diverse group of species and their diploid and polyploid hybrids that are widely cultivated in the tropics. In spite of their socio-economic importance, the knowledge of Musaceae genomes is basically limited to draft genome assemblies of two species, Musa acuminata and M. balbisiana. Here we aimed to complement this information by a...
DNA base sequence comparisons demonstrate that the principal family of 300-nucleotide interspersed human DNA sequences, the repetitive double-strand regions of HeLa cell heterogeneous nuclear RNA, and specific RNA polymerase III in vitro transcripts of cloned human DNA sequences are all representatives of a closely related family of sequences. A segment of approximately 30 residues of these seq...
