A recent Nature publication describes large RNAs that are coded for in the genome, apparently have important functions in the cell, and are not translated into proteins. (The article explaining how they reached their conclusions is well worth the read.)
Why this matters: The classic view of our DNA was that some of the regions of the DNA coded for genes, and some did not. The coding areas were ultimately expressed as proteins; the non-coding areas were a bit of a mystery. For awhile they were written off as "junk DNA" - useless DNA that didn't benefit the cell. Recent research has overturned this notion; for instance, the long RNAs in this article were found in the "junk DNA." Research like this moves us away from our flat DNA-to-protein view, and deepens it to a more complete understanding of how life functions.
Can you tell me something about the cellular damage?

While this is a little more frequent than most car manufacturers recommend, it will ensure that fuel filter problems will be a thing of the past.
