>that is not correct either. For more information, read up on epigenetics.
Epigenetics does not violate the central dogma of molecular biology. Copy-paste from wikipedia:
>These epigenetic changes may last through cell divisions for the duration of the cell's life, and may also last for multiple generations even though they do not involve changes in the underlying DNA sequence of the organism;[5] instead, non-genetic factors cause the organism's genes to behave (or "express themselves") differently.
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'.
