(Phys.org)—Transposable elements—or transposons—are DNA sequences that move in the genome from one location to another. Discovered in the 1940s, for years they were thought to be unimportant and were called "junk DNA." ...

The Y chromosome is a never-ending source of fascination (particularly to men) because it bears genes that determine maleness and make sperm. It's also small and seriously weird; it carries few genes and is full of junk DNA ...

Since the 1960s, it's largely been assumed that most of the DNA in the human genome was junk. It didn't encode proteins—the main activity of our genes— so it was assumed to serve no purpose. But Assistant Professor of ...
