About half of our genome is made up of transposable elements (TEs), also known as transposons. These 'jumping genes' are short stretches of DNA that have the unique ability to duplicate themselves and change their position ...
A study from Massachusetts General Hospital (MGH) investigators has found a surprising role for what had been considered a nonfunctional "junk" RNA molecule: controlling the cellular response to stress. In their report in ...

On the journey from gene to protein, a nascent RNA molecule can be cut and joined, or spliced, in different ways before being translated into a protein. This process, known as alternative splicing, allows a single gene to ...

In one of the mysteries of mammalian development, every cell in the early female embryo shuts down one of its two copies of the X chromosome, leaving just one functional. For years, the mechanics behind this X chromosome ...
