Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a ...

Heterochromatin, sometimes known as the “dark side of the genome,” is a poorly studied fraction of DNA that makes up about half of our genetic material. For more than 50 years scientists have puzzled ...

The human genome, an intricate tapestry of genetic information for life, has proven to be a treasure trove of strange features. Among them are segments of DNA that can "jump around" and move within ...

Sankey diagram illustrating the inferred functions of TE-proximal genes. The width of connections between each vertical block represents the gene count, delineating GO term classifications associated ...

Duke researchers find a surprising genetic source of lethal mutations in fruit flies, with possible implications for conservation and health Scientists have puzzled for decades over a basic ...

Around 45 percent of human DNA is made up of transposable elements, or TEs—genetic leftovers from now-extinct viruses that scientists once believed to be “junk DNA.” But that view is changing, and a ...

There are probably around 20,000 genes in the human genome that code for protein, and cells have to transcribe DNA sequences into RNA, which is then processed before it is translated into proteins by ...

To understand how organisms are related, researchers use molecular information to construct phylogenetic trees. Most of the time, scientists use thousands of protein-coding sequences to determine ...
