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 ...

This schematic illustrates how transposable elements, derived from functional RNAs or retroviruses, shape the human genome and act as regulatory DNA elements. It highlights their essential roles in ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors’ ...
