Recent evidence suggests that some non-coding DNA may be employed by proteins created from coding DNA. An experiment concerning the relationship between introns and coded proteins provided evidence that some non-coding DNA is just as important as coding DNA. This experiment consisted of damaging a portion of noncoding DNA in a plant which resulted in a significant change in the leaf structure because structural proteins depended on information contained in introns. Some non-coding DNA are genetic "switches" that do not encode proteins, but do regulate when and where genes are expressed.
Some non-coding DNA can be a non phenotypical RNA virus historical relic that, by chance, happened to provide some benefit and was therefore conserved.
