Question

Quizplus · Accepted Answer

Through the comparison of mouse and human genomes, researchers have discovered that much of the so-called "junk" DNA actually serves important functional roles in regulating gene expression and other cellular processes. This was an unexpected finding as "junk" DNA was previously thought to be non-functional and not subject to selective pressure.
