Junk DNA necessary for life? (Introduction)

Since their evolutionary split 87 million years ago, both plants have experienced episodes of genetic duplication where the plants' DNA doubled in size. But while the tomato has held onto a lot of those duplicates, the bladderwort has thrown out anything it doesn't need, and now has a genome only a tenth as long as the tomato's. The finding, published online today in Nature, overturns the notion that this repetitive, non-coding DNA, popularly called "junk" DNA, is necessary for life. [/i]

This is what ENCODE tended to show. For very complex DNA, some 3-d spacing arangments are necessary, and so the so-called junk really is useful, but not in a coding way. I think Nature is not clear in their thinking My conclousion is: 'it depends' on which DNA is at work for which organism. One snowball doesn't make a snow storm.
