Note that the original quote is a common misunderstanding of the central dogma, and is incorrect (for example reverse transcription RNA --> DNA is common in nature). The central dogma was invented by Crick, and states that once sequential nucleic acid information (either DNA or RNA) has passed into protein, it cannot be recovered. This has never been violated. Amusingly, it was none other than Crick's pal Watson who popularized the incorrect version via his college textbook, and it is this incorrect version that is regularly announced to have been 'disproven'.
