Question

Quizplus · Accepted Answer

Current scientific thought suggests that only a small part of the genome is made up of protein-coding genes, and a much larger part regulates the activity of genes. This noncoding DNA includes enhancers, silencers, and other regulatory elements that control when and where genes are expressed. The idea of "junk" DNA, or nonfunctional DNA, has largely been debunked as new research shows that much of this noncoding DNA plays important roles in regulating gene expression.
