Stop the Press - Genes Have Regulatory Sequences!

You heard it here first—well, not exactly. The breaking news was first reported over at Biology News Net. Junk DNA isn't junk at all because it's full of regulatory regions controlling gene expression. This is excuse #5 of The Deflated Ego Problem.

Here's the scoop from More 'functional' DNA in genome than previously thought.
Surrounding the small islands of genes within the human genome is a vast sea of mysterious DNA. While most of this non-coding DNA is junk, some of it is used to help genes turn on and off. As reported online this week in Genome Research, Hopkins researchers have now found that this latter portion, which is known as regulatory DNA and contributes to inherited diseases like Parkinson’s or mental disorders, may be more abundant than we realize.
