Phylogeography of human Y-chromosome haplogroup Q3-L275 from an academic/citizen science collaboration

The Y-chromosome haplogroup Q has three major branches: Q1, Q2, and Q3. Q1 is found in both Asia and the Americas where it accounts for about 90% of indigenous Native American Y-chromosomes; Q2 is found in Nor...

Genomic landscape of CpG rich elements in human

The studies on CpG islands (CGI) and Alu elements functions, evolution, and distribution in the genome started since the discovery in nineteen eighties (1981, 1986, correspondingly). Their highly skewed genome...

Mix-and-matching as a promoter recognition mechanism by ECF σ factors

Transcription initiation is in bacteria exhibited by different σ factors, most of which fall within σ⁷⁰ family. This family is diverse, ranging from the housekeeping Group I (RpoDs), to Group IV (ECF) σ factors, ...

In silico evolution of the Drosophila gap gene regulatory sequence under elevated mutational pressure

Cis-regulatory sequences are often composed of many low-affinity transcription factor binding sites (TFBSs). Determining the evolutionary and functional importance of regulatory sequen...

Molecular cytogenetic analysis reveals the existence of two independent neo-XY sex chromosome systems in Anatolian Pamphagidae grasshoppers

Neo-XY sex chromosome determination is a rare event in short horned grasshoppers, but it appears with unusual frequency in the Pamphagidae family. The neo-Y chromosomes found in several species appear to have ...
