During the process of transcription, DNA is converted to RNA, a complex molecule that is able to carry genetic information outside of the cell's nucleus. This page guides you through the biochemical ...

One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code ...

What are introns and why are our genes full of them? This film explores some of the proposed explanations for introns being so common in DNA. with the Breaking Science News daily newsletter ...

Researchers have long puzzled over why many eukaryotic protein-coding genes are interspersed with segments of noncoding DNA that have no obvious biological function. These so-called introns are ...
