Researchers: Junk DNA may have affected human uniqueness
From ScienceDaily: Duplications of large segments of noncoding [junk] DNA in the human genome may have contributed to the emergence of differences between humans and nonhuman primates, according to results presented at the American Society of Human Genetics (ASHG) 2017 Annual Meeting in Orlando, Fla. Identifying these duplications, which include regulatory sequences, and their effect on traits and behavior may help scientists explain genetic contributions to human disease. Paulina Carmona-Mora, PhD, who presented the work; Megan Dennis, PhD; and their colleagues at the University of California, Davis, study the history of human-specific duplications (HSDs), segments of DNA longer than 1,000 base pairs that are repeated in humans but not in primates or other animals. In this study, they focused on Read More ›
