Platforms for investigating lncRNA functions

To aid in the discovery and understanding of lncRNA biology, newly published work from Richard and Eichhorn in SLAS Technology features the technological platforms and methodology presently used to identify the roles of lncRNA ...

Scientists discover a role for 'junk' DNA

Researchers at the University of Michigan Life Sciences Institute and the Howard Hughes Medical Institute have determined how satellite DNA, considered to be "junk DNA," plays a crucial role in holding the genome together.

Plant genes may lack off switch, but have volume control

Scientists at the University of California, Davis have discovered that DNA sequences thought to be essential for gene activity can be expendable. Sequences once called junk sometimes call the shots instead.

Rare evolutionary event detected in the lab

It took nearly a half trillion tries before researchers at The University of Texas at Austin witnessed a rare event and perhaps solved an evolutionary puzzle about how introns, non-coding sequences of DNA located within genes, ...

DNA dumpster diving

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 ...

Sex, genes, the Y chromosome and the future of men

The Y chromosome, that little chain of genes that determines the sex of humans, is not as tough as you might think. In fact, if we look at the Y chromosome over the course of our evolution we've seen it shrink at an alarming ...

What happens when good genes get lost?

Scientifically speaking, there is no bad DNA, though we like to blame it for unruly hair, klutziness or poor gardening skills. There is, however, junk DNA.

New functions for 'junk' DNA?

DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding DNA determines the ...
