Ribosomal DNA (rDNA) sequences are essential parts of many species' genomes. The highly repetitive nature of these DNA sequences makes them susceptible to shrinkage over time—and if they shrink too ...

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 ...

For more than three decades, researchers studying genomes have relied on foundational resources such as Repbase and, more recently, Dfam to identify and classify transposable elements—the mobile DNA ...
