"These findings join a growing body of evidence that the classic "central dogma" of genetics is incomplete. In the central dogma, chromosomal DNA is transcribed into RNA, which is then translated by the cell into proteins. In recent years, however, scientists have found that not all transcribed RNA molecules become translated into proteins. In fact, studies have shown that whole swathes of the genome are transcribed for unknown reasons."
Heh. siRNAs, snoRNAs, now long ncRNAs. Add to that funky splicing of RNA and proteins and the Central Dogma seems like an oversimplification. I was never taught Central Dogma thinking, and cringed when folks would use it in presentations. Biology is messy and the Central Dogma really doesn't capture it. 🙂
