Here is a guest post that Dan Graur didn’t write:
Dear ENCODE researchers,
First of all, allow me to congratulate you on delivering such a large and complex project. The results of your research will benefit many 100s of scientists throughout the world, and the resources generated are invaluable.
However, I have to disagree with the headline figure that 80% of the genome is functional. This contradicts much of the research in this area, and I feel you have used an incorrect definition of the term “functional”.
Specifically:
- Transcription does not equal function
- Histone modification does not equal function
- Open chromatin does not equal function
- Transcription-factor binding does not equal function
- DNA-methylation does not equal function
It is unfortunate that the headline figure of 80% functionality has taken away much focus from the success of the project. It is also unfortunate how many journalists treated this particular piece of information.
However, I do appreciate that science, like many other disciplines, requires, and benefits from, people with opposing views. Your view of functionality certainly opposes mine; however, at the very least, what you have achieved is to stimulate debate on the topic, which is of benefit to everyone
Regards
