(Phys.org)—In the past, geneticists focused primarily on the evolution of genes in order to trace the relationships between species. More recently, genetic elements called SINEs (short interspersed elements) have emerged ...
Despite the sheer number of genes that each human cell contains, these so-called "coding" DNA sequences comprise just 1% of our entire genome. The remaining 99% is made up of "non-coding" DNA—which, unlike coding DNA, does ...
